Move the container wait logic into its own wait_for_container() function
and add two status codes: CONTAINER_TERMINATED or CONTAINER_REBOOTED.
The status will be stored in its argument, this way we handle:
a) Return negative on failures.
b) Return zero on success and set the status to either
CONTAINER_REBOOTED or CONTAINER_TERMINATED.
These status codes are used to terminate nspawn or loop again in case of
CONTAINER_REBOOTED.
There was this code:
if (to_path_len > 0)
memcpy(p, to_path, to_path_len);
That didn't add the terminating zero, so the resulting string was
corrupt if this code path was taken.
Using strcpy() instead of memcpy() solves this issue, and also
simplifies the code.
Previously there was special handling for shortening "../../" to
"../..", but that has now been replaced by a path_kill_slashes() call,
which also makes the result prettier in case the input contains
redundant slashes that would otherwise be copied to the result.
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.

There is also this one genrated by LTO, IMO it's a false positive since
we do *check* for "lease" but the code is not consistent since in that
code path, "lease" is initialized to NULL in other places, except for
this one:
src/resolve/resolved-manager.c: In function 'manager_update_resolv_conf':
src/libsystemd-network/sd-dhcp-lease.c:67:18: warning: 'lease' may be used uninitialized in this function [-Wmaybe-uninitialized]
if (lease->dns_size) {
^
src/network/sd-network.c:146:24: note: 'lease' was declared here
sd_dhcp_lease *lease;
^
This undoes part of commit e6a4a517be.
Instead of removing the error message about non-empty journal bind mount
directories, simply downgrade the message to a warning and proceed.
Only accept cpu quota values in percentages, get rid of period
definition.
It's not clear whether the CFS period controllable per-cgroup even has a
future in the kernel, hence let's simplify all this, hardcode the period
to 100ms and only accept percentage based quota values.

Currently if nspawn was called with --link-journal=host or
--link-journal=auto and the right /var/log/journal/machine-id/ exists
then the bind mount the subdirectory into the container might fail due
to the ~/mycontainer/var/log/journal/machine-id/ of the container not
being empty.
There is no reason to check if the container journal subdir is empty
since there will be a bind mount on top of it. The user asked for a bind
mount so give it.
Note: a next call with --link-journal=guest may fail due to the
/var/log/journal/machine-id/ on the host not being empty.

The verbose link-time deprecation warnings are annoying. These libs
will never change or be extended; there is no need to test the list
of exported symbols.
./.libs/libsystemd-network.a(libsystemd_network_la-network-internal.o):
network-internal.c:function net_get_unique_predictable_data:
error: undefined reference to 'udev_device_get_property_value'

Similar to CPUShares= and BlockIOWeight= respectively. However only
assign the specified weight during startup. Each control group
attribute is re-assigned as weight by CPUShares=weight and
BlockIOWeight=weight after startup. If not CPUShares= or
BlockIOWeight= be specified, then the attribute is re-assigned to each
default attribute value. (default cpu.shares=1024, blkio.weight=1000)
If only CPUShares=weight or BlockIOWeight=weight be specified, then
that implies StartupCPUShares=weight and StartupBlockIOWeight=weight.
