Package: systemd
Version: 204-14
Severity: normal
Hi,
my host system is jessie. In my sid-amd64 chroot which I entered using
systemd-nspawn, I tried to start a new systemd --system instance:
$ sudo systemd-nspawn -D /srv/src/chroot/sid-amd64
Spawning namespace container on /srv/src/chroot/sid-amd64 (console is /dev/pts/4).
Init process in the container running as PID 27787.
/etc/localtime is not a symlink, not updating container timezone.
