ecde7065f7 units: rebuild /etc/passwd, the udev hwdb and the journal catalog files on boot
Only when necessary of course, nicely guarded with the new
ConditionNeedsUpdate= condition we added.

55152b6ede units: pull in time-sync.target from systemd-timedated.service
After all, that's what we document for time-sync.target in
systemd.special(5), hence let's follow our own suggestion.

1b8689f949 core: rename ReadOnlySystem= to ProtectSystem= and add a third value for also mounting /etc read-only
Also, rename ProtectedHome= to ProtectHome=, to simplify things a bit.

With this in place we now have two neat options ProtectSystem= and
ProtectHome= for protecting the OS itself (and optionally its
configuration), and for protecting the user's data.

417116f234 core: add new ReadOnlySystem= and ProtectedHome= settings for service units
ReadOnlySystem= uses fs namespaces to mount /usr and /boot read-only for
a service.

ProtectedHome= uses fs namespaces to mount /home and /run/user
inaccessible or read-only for a service.

This patch also enables these settings for all our long-running services.

Together they should be good building block for a minimal service
sandbox, removing the ability for services to modify the operating
system or access the user's private data.

d636d37679 timesyncd: only update stamp file when we are synchronized
Create initial stamp file with compiled-in time to prevent bootups
with clocks in the future from storing invalid timestamps.

At shutdown, only update the timestamp if we got an authoritative
time to store.

ece6e766cf timesyncd: save clock to disk everytime we get an NTP fix, and bump clock at boot using this
This is useful to make sure the system clock stays monotonic even on
systems that lack an RTC.

Also, why we are at it, also use the systemd release time for bumping
the clock, since it's a slightly less bad than starting with jan 1st,
1970.

This also moves timesyncd into the early bootphase, in order to make
sure this initial bump is guaranteed to have finished by the time we
start real daemons which might write to the file systemd and thus
shouldn't leave 1970's timestamps all over the place...

0968137439 timesyncd: start after networkd
This is needed for the network monitor to work (as it requires networkd to set up the correct directories first).
