If the input timestamp is too old (say, 1min since 1970-01-01), then
parse_timestamp() may fail on a timezone with positive shift e.g.
JST (UTC+9). Moreover, even if parse_timestamp() succeeds, its result
'y' and 'usec_sub_unsigned(x, 2 * USEC_PER_DAY)' are both zero, and
the assertion will be triggered.
docs: tweak rsync flags for moving existing home dir to systemd-homed
The documentation on moving an existing homedir into a systemd-homed managed
one suggests using rsync(1) with a bunch of flags to preserve as much metadata
as possible: permissions, xattrs, timestamps, etc. The previously suggested
flags were:
rsync -aHAXv --remove-source-files …
… which does include mtimes, but not ctimes and atimes, because -a does not
include those:
--archive, -a archive mode is -rlptgoD (no -A,-X,-U,-N,-H)
This change adds the -N and -U flags to preserve even more file timestamps,
turning the command into:
rsync -aHANUXv --remove-source-files …
The new flags are:
--crtimes, -N preserve create times (newness)
--atimes, -U preserve access (use) times

core: split system/user job timeouts and make them configurable
Config options are -Ddefault-timeout-sec= and -Ddefault-user-timeout-sec=.
Existing -Dupdate-helper-user-timeout= is renamed to -Dupdate-helper-user-timeout-sec=
for consistency. All three options take an integer value in seconds. The
renaming and type-change of the option is a small compat break, but it's just
at compile time and result in a clear error message. I also doubt that anyone was
actually using the option.
This commit separates the user manager timeouts, but keeps them unchanged at 90 s.
The timeout for the user manager is set to 4/3*user-timeout, which means that it
is still 120 s.
Fedora wants to experiment with lower timeouts, but doing this via a patch would
be annoying and more work than necessary. Let's make this easy to configure.
basic/user-util: create /etc from take_etc_passwd_lock

journal-file: refuse writing to journal files where the header size is different then expected
We keep adding fields to the header, and it's fine reading files with
different header sizes, as we check via the size if the fields we need
are included. However, let's be stricter when writing journal files than
when reading, and insist that the header structure in the file actually
matches our expectations. Refuse otherwise, so that a new file is
created after rotation that then matches our expectations.
This makes sure that mismatch in header size is treated exactly as
unknown "compatible" flags, which is our other mechanism to allow
extending the journal file format in a non-breaking way.
In https://bugzilla.redhat.com/show_bug.cgi?id=2156900 sysusers was reporting a
conflict between the following lines:
u root 0:0 "Super User" /root /bin/bash
u root 0 "Super User" /root
The problem is that those configurations are indeed not equivalent. If group 0
exists with a different name, the first line would just create the user, but the
second line would create a 'root' group with a different GID. The second
behaviour seems definitely wrong. (Or at least more confusing in practice than
the first one. The system is in a strange shape, but the second approach takes
an additional step than is worse than doing nothing.)
When this line was initially added, we didn't have the uid:gid functionality for
'u', so we didn't think about this too much. But now we do, so we should use it.

network/dhcp4: accept local subnet routes from DHCP
RFC3442 specifies option 121 (Classless Static Routes) that allow a DHCP
server to push arbitrary routes to a client. It has a Local Subnet
Routes section expliciting the behavior of routes with a null (0.0.0.0)
gateway.
Such routes are to be installed on the interface with a Link scope, to
mark them as directly available on the link without any gateway.
Networkd currently drops those routes, which is against the RFC, as
Linux has proper support for such routes.
Fixes: 7f20627 ("network: dhcp4: ignore gateway in static routes if destination is link-local or in the same network")

sleep: introduce SuspendEstimationSec=

However, after 96d662fa4c8cab24da57523c5e49e6ef3967fc13, the setting is
repurposed as the default interval to measure battery charge level and
estimate the battery discharging late. And if the system has enough
battery capacity, then the system will stay in suspend state and not
hibernate even if the time passed. See issue #25269.
To keep the backward compatibility, let's introduce another setting
SuspendEstimationSec= for controlling the interval to measure
battery charge level, and make HibernateDelaySec= work as of v251.
This also drops implementation details from the man page.
