96ba0ca283 For some units, use "systemctl restart" rather than "systemctl stop/start"
During a configuration switch, changed units are stopped in the old
configuration, then started in the new configuration (i.e. after
running the activation script and running "systemctl daemon-reload").
This ensures that services are stopped using the ExecStop/ExecStopPost
commands from the old configuration.

However, for some services it's undesirable to stop them; in
particular dhcpcd, which deconfigures its network interfaces when it
stops.  This is dangerous when doing remote upgrades - usually things
go right (especially because the switch script ignores SIGHUP), but
not always (see 9aa69885f0).  Likewise,
sshd should be kept running for as long as possible to prevent a
lock-out if the switch fails.

So the new option ‘stopIfChanged = false’ causes "systemctl restart"
to be used instead of "systemctl stop" followed by "systemctl start".
This is only proper for services that don't have stop commands.  (And
it might not handle dependencies properly in some cases, but I'm not
sure.)

baac242a1f Run the garbage collector as a systemd service
Running it from systemd rather than cron has several advantages:
systemd ensures that only one instance runs at a time; the GC can be
manually started/stopped; and logging goes to the journal.

We still need cron to start the service at the right time, but
hopefully soon we can get rid of cron entirely (once systemd supports
starting a unit at a specific time).

9aa69885f0 Don't do readlink() on every mount point when remounting /dev etc.
Doing so causes the activation script to hang if (say) an NFS mount
point is unreachable.

16a9bcfe81 add support for systemd mount units
This is mainly useful for specifying mounts that depend on other
units. For example sshfs or davfs need network (and possibly
nameservices).

While systemd makes a distinction between local and remote
filesystems, this only works for in-kernel filesystems such as
nfs and cifs.

fuse-based filesystems (such as sshfs and davs) are classified as
local, so they fail without networking. By explicitly declaring these
mounts as full systemd units (as opposed to having systemd generate
them automatically from /etc/fstab), dependencies can be specified as
on every other unit.

In the future, we can probably port NixOS' filesystems handling to use
these native systemd.mount units and skip /etc/fstab altogether, but
this probably requires additional changes, such as starting systemd
even earlier during boot (stage 1).

358239348a making memtest grub entries work again
I'm not any good at perl, and I only came up with this after many
slow attempts. Any review welcome.

But until this, memtest was broken, and extraPrepareConfig as well, in grub.

bd7ea9be58 sysinit.target: Drop the dependency on local-fs.target and swap.target
Having all services with DefaultDependencies=yes depend on
local-fs.target is annoying, because some of those services might be
necessary to mount local filesystems.  For instance, Charon's
send-keys feature requires sshd to be running in order to receive LUKS
encryption keys, which in turn requires dhcpcd, and so on.  So we drop
this dependency (and swap.target as well for consistency).  If
services require a specific mount, they should use RequiresMountsFor
in any case.

68872f81cf openssh: Change the way authorized keys are added to the system.
Instead of the somewhat hacky script that inserted public keys

configuration directive in sshd_config and generate extra key
files for each user (placed in /etc/authorized_keys.d/).
