udev on exit doesn't unlink control socket nor does systemd. Thus socket
stays around even when both daemon and socket are stopped. This causes
problems for cryptsetup because when it detects running udev it launches
synchronous operations that *really* require udev. This in turn may
cause blocking and subsequent timeout in systemd-cryptsetup on reboot
while machine is in a state that udev and its control socket units are

journal: implicitly flush to var on recovery (#4028)
When the system journal becomes re-opened post-flush with the runtime
journal open, it implies we've recovered from something like an ENOSPC
situation where the system journal rotate had failed, leaving the system
journal closed, causing the runtime journal to be opened post-flush.
For the duration of the unavailable system journal, we log to the
runtime journal. But when the system journal gets opened (space made
available, for example), we need to close the runtime journal before new
journal writes will go to the system journal. Calling
server_flush_to_var() after opening the system journal with a runtime
journal present, post-flush, achieves this while preserving the runtime
journal's contents in the system journal.
The combination of the present flushed flag file and the runtime journal
being open is a state where we should be logging to the system journal,
so it's appropriate to resume doing so once we've successfully opened
the system journal.

terminal-util: remove unnecessary check of result of isatty() (#4000)
After the call of the isatty() we check its result twice in the
open_terminal(). There are no sense to check result of isatty() that
it is less than zero and return -errno, because as described in
documentation:
isatty() returns 1 if fd is an open file descriptor referring to a
terminal; otherwise 0 is returned, and errno is set to indicate the
error.
So it can't be less than zero.

systemd: ignore lack of tty when checking whether colors should be enabled
When started by the kernel, we are connected to the console, and we'll set TERM
properly to some value in fixup_environment(). We'll then enable or disable
colors based on the value of $SYSTEMD_COLORS and $TERM.
When reexecuting, TERM should be already set, so we can use this value.

affd7ed1a was reverted, but instead
of reopening the console before configuring color output, we just ignore what
stdout is connected to and decide based on the variables only.

.wants/ or .requires/ directory.
2) A unit's purpose may be to act as a helper for some other unit which has
a requirement dependency on it.
3) A unit may be started when needed via activation (socket, path, timer,

It is better to create units in a state that completely matches the presets, i.e.

I'm sure it was confusing to users too, suggesting that system and user units
may somehow alias each other.

shared/install: ignore unit symlinks when doing preset-all
Before, when interating over unit files during preset-all, behaviour was the
following:
- if we hit the real unit name first, presets were queried for that name, and
that unit was enabled or disabled accordingly,
- if we hit an alias first (one of the symlinks chaining to the real unit), we
checked the presets using the symlink name, and then proceeded to enable or
disable the real unit.
E.g. for systemd-networkd.service we have the alias dbus-org.freedesktop.network1.service
(/usr/lib/systemd/system/dbus-org.freedesktop.network1.service), but the preset
is only for the systemd-networkd.service name. The service would be enabled or
disabled pseudorandomly depending on the order of iteration.
For "preset", behaviour was analogous: preset on the alias name disabled the
service (following the default disable policy), preset on the "real" name
applied the presets.
With the patch, for "preset" and "preset-all" we silently skip symlinks. This
gives mostly the right behaviour, with the limitation that presets on aliases
are ignored. I think that presets on aliases are not that common (at least my
preset files on Fedora don't exhibit any such usage), and should not be
necessary, since whoever installs the preset can just refer to the real unit
file. It would be possible to overcome this limitation by gathering a list of
names of a unit first, and then checking whether *any* of the names matches the
presets list. That would require a significant redesign of the code, and be
a lot slower (since we would have to fully read all unit directories to preset
one unit) to so I'm not doing that for now.
With this patch, two properties are satisfied:
- preset-all and preset are idempotent, and the second and subsequent invocations
do not produce any changes,
- preset-all and preset for a specific name produce the same state for that unit.
Fixes #3616.
