This is currently our only .automount unit. We wouldn't want to trigger it
accidentally during shutdown, so let's stop it too.

Commit 42cc2855ba2fe4c6f5d incorrectly removed the condition on sysfs in both
sys-fs-fuse-connections.mount and sys-kernel-config.mount. However there are
still needed in case modprobe of one of these modules is intentionally skipped
(due to lack of privs for example).
This patch restores the 2 conditions which should be safe for the common case,
since all conditions are only checked after all deps ordered before are
complete.
Follow-up for 42cc2855ba2fe4c6f5dc863507a1c843611350a0.

udev requests to start the fs mount units when their respective module is
loaded. For that it monitors uevents of type "ADD" for the relevant fs modules.
However the uevent is sent by the kernel too early, ie before the init() of the
module is called hence before directories in /sys/fs/ are created.
This patch workarounds adds "Requires/After=modprobe@<fs-module>.service" to
the mount unit, which means that modprobe(8) will be called once the fs module
is announced to be loaded. This sounds pointless, but given that modprobe only
returns after the initialization of the module is complete, it should
workaround the issue.
As a side effect, the module will be automatically loaded if the mount unit is
started manually.
Fixes#17586.

This reverts commit 9cbf1e58f9629af5c6b56777ee73dc6320306d6d.
The presence of /sys/module/%I directory can't be used to assert that the load
of a given module is complete and therefore the call to modprobe(8) can be
skipped. Indeed this directory is created before the init() function of the
module is called.
Users of modprobe@.service needs to be sure that once this service returns the
module is fully operational.

[zjs: Replaces #17149.
I took half of the patch in
https://github.com/systemd/systemd/pull/17149#issuecomment-698399194,
hence I'm keeping Jonathan's authorship.
The original reasoning for 6c5496c492a8d74e54d22bf8824160cab1e63c10 was that we
enable remote-cryptsetup.target via presets, and since presets are not used for
the initrd, we need a different target. But since parts of the unit and target
tree are shared between the initramfs and the main system, we can't just create
a separate target for the initramfs. All the targets that depend on this one
would need to be split also. That condition is true for initrd-fs.target, but
not for sysinit.target.
So let's instead just uncoditionally pull in remote-cryptsetup.target in the
initramfs. It should normally be empty, so there should be no impact on boots
that don't have units in the target.
Jonathan's patch used initrd-root-fs.target, this version instead uses
initrd-root-device.target. initrd-root-device.target is ordered before
sysroot.mount, which means that the decrypted devices will be available earlier
too.]

The ext4 fs resize ioctl needs CAP_SYS_RESOURCE, irritatingly. Let's
grant it to homed hence.
Fixes: #15115
(cherry picked from commit c9ef77ec5ff5e7e283181e9dcfb93acfb0656ae6)
This should make /home as automount work reasonably well.
If /home is an automount this has little effect at boot, because if the
automount is not triggered it doesn't matter how the associated mount is
ordered.
It does matter at shutdown however, where home.mount is likely active
now. There the ordering means we'll end sessions first, and only then
deactivate home.mount.

RC_LOCAL_SCRIPT_PATH_START and RC_LOCAL_SCRIPT_PATH_STOP were was originally

44508946534eee032927c263b79464832656dd6e RC_LOCAL_SCRIPT_PATH_STOP was dropped.
We don't need to use such a long name.

This should be enough to fix https://bugzilla.redhat.com/show_bug.cgi?id=1856514.
But the limit should be significantly higher than 10% anyway. By setting a
limit on /tmp at 10% we'll break many reasonable use cases, even though the
machine would deal fine with a much larger fraction devoted to /tmp.
(In the first version of this patch I made it 25% with the comment that
"Even 25% might be too low.". The kernel default is 50%, and we have been using
that seemingly without trouble since https://fedoraproject.org/wiki/Features/tmp-on-tmpfs.
So let's just make it 50% again.)
See 7d85383edbab73274dc81cc888d884bb01070bc2.
(Another consideration is that we learned from from the whole initiative with
zram in Fedora that a reasonable size for zram is 0.5-1.5 of RAM, and that pretty
much all systems benefit from having zram or zswap enabled. Thus it is reasonable
to assume that it'll become widely used. Taking the usual compression effectiveness
of 0.2 into account, machines have effective memory available of between
1.0 - 0.2*0.5 + 0.5 = 1.4 (for zram sized to 0.5 of RAM) and
1.0 - 0.2*1.5 + 1.5 = 2.2 (for zram 1.5 sized to 1.5 of RAM) times RAM size.
This means that the 10% was really like 7-4% of effective memory.)
A comment is added to mount-util.h to clarify that tmp.mount is separate.
This reverts commit c7220ca8025e8dbded36131b23a502d975c45754.
The removal was done as a reaction to the messages from systemd:
initrd-root-fs.target: Requested dependency OnFailure=emergency.target ignored (target units cannot fail).
initrd.target: Requested dependency OnFailure=emergency.target ignored (target units cannot fail).
initrd-root-device.target: Requested dependency OnFailure=emergency.target ignored (target units cannot fail).
initrd-fs.target: Requested dependency OnFailure=emergency.target ignored (target units cannot fail).
local-fs.target: Requested dependency OnFailure=emergency.target ignored (target units cannot fail).
...
But it seems that the messages themselves are wrong, and the units were OK.
Strictly speaking you can run homed without userdb. But it doesn't
really make much sense: they go hand in hand and implement the same
concepts, just for different sets of users. Let's hence disable both
automatically by default if homed is requested.
(We don't do the reverse: opting into userdbd shouldn't mean that you
are OK with homed.)
And of course, users can always deviate from our defaults easily, and
turn off userbd again right-away if they don't like it, and things will
generally work.
This generator can be used by desktop environments to launch autostart
applications and services. The feature is an opt-in, triggered by
xdg-desktop-autostart.target being activated.
Also included is the new binary xdg-autostart-condition. This binary is
used as an ExecCondition to test the OnlyShowIn and NotShowIn XDG
desktop file keys. These need to be evaluated against the
XDG_CURRENT_DESKTOP environment variable which may not be known at
generation time.

In our regular gettys the actual shell commands live the the session
scope anyway (as long as logind is used). Hence, let's avoid
KillMode=process, it serves no purpose and is simply unsafe since it
disables systemd's own process lifecycle management.
We want to watch USB sticks being plugged in, and that requires
AF_NETLINK to work correctly and get the host's events. But if we live
in a network namespace AF_NETLINK is disconnected too and we'll not get
the host udev events.
Fixes: #15287
Limit size of various tmpfs mounts to 10% of RAM, except volatile root and /var
to 25%. Another exception is made for /dev (also /devs for PrivateDevices) and
/sys/fs/cgroup since no (or very few) regular files are expected to be used.
In addition, since directories, symbolic links, device specials and xattrs are
not counted towards the size= limit, number of inodes is also limited
correspondingly: 4MB size translates to 1k of inodes (assuming 4k each), 10% of
RAM (using 16GB of RAM as baseline) translates to 400k and 25% to 1M inodes.
Because nr_inodes option can't use ratios like size option, there's an
unfortunate side effect that with small memory systems the limit may be on the
too large side. Also, on an extremely small device with only 256MB of RAM, 10%
of RAM for /run may not be enough for re-exec of PID1 because 16MB of free
space is required.
"Login Service" doesn''t explain much, esp. considering that logind is actually is
for logins. I think "User Login Management" is better, but not that great either.
Suggestions welcome.
We unregister binfmt_misc twice during shutdown with this change:
1. A previous commit added support for doing that in the final shutdown
phase, i.e. when we do the aggressive umount loop. This is the robust
thing to do, in case the earlier ("clean") shutdown phase didn't work
for some reason.
2. This commit adds support for doing that when systemd-binfmt.service
is stopped. This is a good idea so that people can order mounts
before the service if they want to register binaries from such
mounts, as in that case we'll undo the registration on shutdown
again, before unmounting those mounts.
And all that, just because of that weird "F" flag the kernel introduced
that can pin files...
Fixes: #14981
This doesn't really matter, since in non-/usr-merged systems plymouth
needs to be in /bin and on merged ones it doesn't matter, but it is
still prettier to insert the right path, and avoid /bin on merged
systems, since it's just a compat symlink.
Replaces: #15351
This dependency is now generated automatically given we use
StateDirectory=. Moreover the combination of Wants= and After= was too
strong anway, as whether remount-fs is pulled in or not should not be up
to systemd-pstore.service, and in fact is part of the initial
transaction anyway.
sysinit.target is the target our early boot services are generally
pulled in from, make systemd-pstore.service not an exception of that.
Effectively this doesn't mean much, either way our unit is part of the
initial transaction.
Add `ProtectClock=yes` to systemd units. Since it implies certain
`DeviceAllow=` rules, make sure that the units have `DeviceAllow=` rules so
they are still able to access other devices. Exclude timesyncd and timedated.
This reverts commit 7e1ed1f3b29162df25064b33dc55ac8cf432bb0b.
systemd-repart is not a user service that should be something people
enable/disable, instead it should just work if there's configuration for
it. It's like systemd-tmpfiles, systemd-sysusers, systemd-load-modules,
systemd-binfmt, systemd-systemd-sysctl which are NOPs if they have no
configuration, and thus don't hurt, but cannot be disabled since they
are too deep part of the OS.
This doesn't mean people couldn't disable the service if they really
want to, there's after all "systemctl mask" and build-time disabling,
but those are OS developer facing instead of admin facing, that's how it
should be.
Note that systemd-repart is in particular an initrd service, and so far
enable/disable state of those is not managed anyway via "systemctl
enable/disable" but more what dracut decides to package up and what not.
/home is posibly a remote file system. it makes sense to order homed
after it, so that we can properly enumerate users in it, but we probably
shouldn't pull it in ourselves, and leave that to users to configure
otherwise.
Fixes: #15102
It's lightweight and generally useful, so it should be enabled by default. But
users might want to disable it for whatever reason, and things should be fine
without it, so let's make it installable so it can be disabled if wanted.
Fixes#15175.
This essentially adds another layer of configurability:
build disable, this, presence of configuration. The default is
set to enabled, because the service does nothing w/o config.
