2e72b79459 Fix for dst/non-dst timezones
The problem was with the tm.tm_isdst that is set to the current environment
value: either DST or not. While the current state is not relevant to the state
in the desired date.

Hence — it should be reset so that the mktime_or_timegm could normalise it
later.

1245e4132b man: use "filename" not "file name" by default
We settled on "filename" and "file system", so change a couple of places for
consistency. The exception is when there's an adjective before "file" that
binds more strongly then "name": "password file name", "output file name", etc.
Those cases are left intact.

0b1f68ac87 cryptsetup: make sure we invoke the cryptsetup tools with a shared keyring
We want that cryptsetup can cache keys between multiple invocations, and
it does so via the root user's user keyring, hence let's share it among
services.

b1edf4456e core: add new per-unit setting KeyringMode= for controlling kernel keyring setup
Usually, it's a good thing that we isolate the kernel session keyring
for the various services and disconnect them from the user keyring.
However, in case of the cryptsetup key caching we actually want that
multiple instances of the cryptsetup service can share the keys in the
root user's user keyring, hence we need to be able to disable this logic
for them.

This adds KeyringMode=inherit|private|shared:

    inherit: don't do any keyring magic (this is the default in systemd --user)
    private: a private keyring as before (default in systemd --system)
    shared: the new setting

- umount -c now really works (partially solves #6115).

of the provided search domain is applied, after which the search
list is written in wire format into the DNSSL option.

6e2f5000c7 man: delete note about propagating signal termination
That advice is generally apropriate for "user" programs, i.e. programs which
are run interactively and used pipelines and such. But it makes less sense for
daemons to propagate the exit signal. For example, if a process receives a SIGTERM,
it is apropriate for it to exit with 0 code. So let's just delete the whole
paragraph, since this page doesn't seem to be the right place for the longer
discussion which would be required to mention all the caveats and considerations.

Fixes #6415.

ab2116b140 core: make sure that $JOURNAL_STREAM prefers stderr over stdout information (#6824)
If two separate log streams are connected to stdout and stderr, let's
make sure $JOURNAL_STREAM points to the latter, as that's the preferred
log destination, and the environment variable has been created in order
to permit services to automatically upgrade from stderr based logging to
native journal logging.

Also, document this behaviour.

bce67bbee3 networkd: add support to configure IP Rule (#5725)
Routing Policy rule manipulates rules in the routing policy database control the
route selection algorithm.

This work supports to configure Rule
```
[RoutingPolicyRule]
TypeOfService=0x08
Table=7
From= 192.168.100.18

```

```
ip rule show
0:	from all lookup local
0:	from 192.168.100.18 tos 0x08 lookup 7
```

V2 changes:

1. Added logic to handle duplicate rules.
2. If rules are changed or deleted and networkd restarted
   then those are deleted when networkd restarts next time

V3:

1. Add parse_fwmark_fwmask

f1e24a259c units: don't kill the emergency shell when sysinit.target is triggered (#6765)
Why
---

The advantage of this is that starting sysinit.target from the emergency
shell will no longer kill the emergency shell and lock you out of the
system.  Our docs already claimed that emergency.target was useful for
"starting individual units in order to continue the boot process in steps".
This resolves #6509 for my purposes.

Remaining limitation
--------------------

Starting getty.target will still kill the shell, and if you don't have a
root password you will then be locked out at that point.  This is relevant
to distributions which patch the sulogin system to permit logins when the
root password is locked.  Both Debian and RedHat used to follow this
behaviour!  Debian have been discussing what they could replace it with at
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=806852

So this doesn't quite achieve perfection, but I think it's a worthwhile
change.  It should be easier to understand the logic now it doesn't have
such a big hole in it.  Repairing the sysinit stage of the boot is the main
reason we have emergency.target.  And as discussed in the issue,
sysinit.target gets pulled in implicitly as soon as any DefaultDependencies
service is activated.

How
---

sysinit.target only needs to conflict with emergency.target.  It didn't
need to conflict with emergency.service as well.  In theory the conflicts
are pointless, we could just change the dependency of sysinit.target on
local-fs.target from Wants to Requires.  However, doing so would mean that
when local-fs fails, the screen is flooded with yellow [DEPEND] failures.
That would hinder the poor unfortunate admin, so let's not do that.

There is no additional ordering requirement against emergency.  If the
failure happens, the job for sysinit will be cancelled instantly.  We don't
need to worry about when sysinit.target and its dependents would be
stopped, because sysinit waits for local-fs before it starts.

emergency.target is still necessarily stopped once we reach sysinit
(you can't express a one-way conflict in pure unit directives).
This is largely cosmetic... though perhaps it symbolizes that you're no
longer in Emergency Mode if System Initialization is successful ;-).

As a secondary advantage, the getty's which conflict on rescue.service now
need to conflict on emergency.service as well.  This makes the system more
uniform and simpler to understand.

The only other effect this should have is that
`systemctl start emergency.target` is now practically the same as
`systemctl start rescue.target`.  The only units this command will stop are
the conflicting getty units.  Neither of those commands should ever be
used.  E.g. they will not stop the gdm.service unit on Fedora 26.

038492aed3 shared: end string with % if one was found at the end of a expandible string (#6828)
Current behavior is that %X where X is an unidentified specifier, then the result is
the same %X string. This was not the case when the string ended with a stray %, where
the character would have not been output. Lets add that missing character.

a1f31f4715 core/manager: when running in test mode, use a temp dir for generated stuff
When running through systemd-analyze verify or with --test, we would
not run generators (environment or unit). But at the end, we would nuke
the generator dirs anyway.

Simplify things by actually running generators of both types, but redirecting
their output to a temporary directory. This has the advantage that we test more
code, and the verification is more complete.

Since now we are not touching the real generator directories, we also don't
delete them, which fixes #5609.
