689aede8c6 fstab-generator: when running in a container, ignore fstab entries referring to device nodes
Since these device nodes will never appear in the container anyway
there's no point in waiting for them.

This makes it easier to boot images generated with general purpose
installers like Anaconda which unconditionally populate /etc/fstab to
boot in containers.

e48fdd8443 generators: rework mount generators
- Add support for finding and mounting /srv based on GPT data, similar
  to how we already handly /home.

- Share the fsck logic between GPT, EFI and fstab generators

- Make sure we never run the EFI generator inside containers

- Drop DefaultDependencies=no from EFI mount units

- Other fixes

141a79f491 Extract looping over /proc/cmdline into a shared function
In cryptsetup-generator automatic cleanup had to be replaced
with manual cleanup, and the code gets a bit longer. But existing
code had the issue that it returned negative values from main(),
which was wrong, so should be reworked anyway.

63a1b905d8 fstab-generator: Create fsck-root symlink with correct path
This was noticed in Brussels at the hackfest. The fstab-generator currently

e2f123b97b fstab-generator: Do not try to fsck non-devices
This fixes a regression introduced in 64e70e4 where the mount fails
when fstab is misconfigured with fs_passno > 0 on a virtual file
system like nfs, and the type is specified as "auto".

4e8da52959 fstab-generator: use RequiresOverridable for fsck units
This allows the user to disable fsck's by masking.

If fsck fails, emergency target is started, the user might mount the
unit using mount and disable fsck by masking the unit. In this case,
.mount will be active because the mount is detect through
/proc/self/mountinfo, but systemd-fsck@.service will still be in
failed mode. This results in a funny situation where

$ systemctl show -p ActiveState local-fs.target yyy.mount
ActiveState=active
ActiveState=active

$ sudo systemctl start local-fs.target
[sudo] password for test:
Failed to start local-fs.target: Unit systemd-fsck@xxx.service is masked.

94192cdaf6 fsck,fstab-generator: be lenient about missing fsck.<type>
If fstab contains 1 for passno, treat this as an error, but only warn
briefly. If fstab doesn't contain this information, don't complain at
all.

Patch is complicated a bit by the fact that we might have the fstype specified
in fstab or on /proc/cmdline, in which case we can check if we have the appropriate
fsck tool, or not specified, or specified as auto, in which case we have to look
and check the type of the filesystem ourselves. It cannot be done before the
device appears, so it is too early in the generator phase, and it must be done
directly in fsck service.

a7623afb7a fsck-root: only run when requested in fstab
fsck-root is redundant in case an initrd is used, or in case the rootfs
is never remounted 'rw', so the new default is the correct behavior for
most users. For the rest, they should enable it in fstab.

7f5806d709 fstab-generator: When parsing the root= cmdline option, set FsckPassNo to 1
[tomegun: without this we would never fsck the rootfs if it was directly
mounted 'rw' from the initrd. We now risk fsck'ing it twice in the case it
is mounted 'ro', so that should be addressed in a separate patch.]

4e82fe5213 swap: create .wants symlink to 'auto' swap devices
As we load unit files lazily, we need to make sure something pulls in swap
units that should be started automatically, otherwise the default dependencies
will never be applied.

This partially reinstates code removed in
commit 64347fc2b9.

Also don't order swap devices after swap.target when they are 'nofail'.

Currently we don't respect noauto/nofail root mount options (from

e8d2f6cde0 units: introduce remote-fs-setup.target to pull in dependencies from remote mounts
This introduces remote-fs-setup.target independently of
remote-fs-pre.target. The former is only for pulling things in, the
latter only for ordering.

The new semantics:

remote-fs-setup.target: is pulled in automatically by all remote mounts.
Shall be used to pull in other units that want to run when at least one
remote mount is set up. Is not ordered against the actual mount units,
in order to allow activation of its dependencies even 'a posteriori',
i.e. when a mount is established outside of systemd and is only picked
up by it.

remote-fs-pre.target: needs to be pulled in automatically by the
implementing service, is otherwise not part of the initial transaction.
This is ordered before all remote mount units.

A service that wants to be pulled in and run before all remote mounts
should hence have:

a) WantedBy=remote-fs-setup.target -- so that it is pulled in

b) Wants=remote-fs-pre.target + Before=remote-fs-pre.target -- so that
   it is ordered before the mount point, normally.

790838e4f1 fstab-generator: rename x-initrd-rootfs.mount to x-initrd.rootfs
This changes the fstab mount option x-initrd-rootfs.mount to
x-initrd.rootfs, in order to only use a single namespace "x-initrd." for

9e5f0f9291 Make initrd.target the default target in the initrd
First, rename root-fs.target to initrd-root-fs.target to clarify its usage.

Mount units with "x-initrd-rootfs.mount" are now ordered before
initrd-root-fs.target. As we sometimes construct /sysroot mounts in
/etc/fstab in the initrd, we want these to be mounted before the
initrd-root-fs.target is active.

initrd.target can be the default target in the initrd.

700e07ffd5 add initrd-fs.target and root-fs.target
Instead of using local-fs*.target in the initrd, use root-fs.target for
sysroot.mount and initrd-fs.target for /sysroot/usr and friends.

Using local-fs.target would mean to carry over the activated
local-fs.target to the isolated initrd-switch-root.target and thus in
the real root. Having local-fs.target already active after
deserialization causes ordering problems with the real root services and
targets.

We better isolate to targets for initrd-switch-root.target, which are
only available in the initrd.

3d22d1ab57 fstab-generator: initrd - mount selected entries from /sysroot/etc/fstab
We only mount "/usr" and entries marked with "x-initrd.mount".

This (together with the right unit files) is needed in the initramfs in order to
natively support mounting /usr (and friends) from the initramfs.

The way it is meant to work is:
 * wait for sysroot.mount to be mounted
 * do a daemon-reload to generate sysroot-usr.mount (++) from /sysroot/etc/fstab
 * wait for sysroot-usr.mount to be mounted
 * switch-root
