[systemd-devel] Problem with LXC and systemd-gpt-auto-generator

[John Lane]

Good evening. I have noticed a problem on systemd 208. I get an odd 
error when trying to enable/disable:

# systemctl disable dhcpcd
rm '/etc/systemd/system/multi-user.target.wants/dhcpcd.service'
<27>systemd-gpt-auto-generator[171]: Failed to verify GPT partition 
/dev/dm-5: No such file or directory

but the link does get removed

# systemctl enable dhcpcd
ln -s '/usr/lib/systemd/system/dhcpcd.service' 
'/etc/systemd/system/multi-user.target.wants/dhcpcd.service'
<27>systemd-gpt-auto-generator[179]: Failed to verify GPT partition 
/dev/dm-5: No such file or directory

but the link does get created

It also happens with 207. If I downgrade to 206 it does not happen.
With
# systemctl --version
systemd 206
+PAM -LIBWRAP -AUDIT -SELINUX -IMA -SYSVINIT +LIBCRYPTSETUP +GCRYPT +ACL +XZ

This is on ArchLinux. I have another container, just created with 
"lxc-create -t lxc-archlinux..." and this shows an error on boot but 
otherwise appears to work:

Failed to verify GPT partition /dev/dm-17: No such file or directory
/usr/lib/systemd/system-generators/systemd-gpt-auto-generator exited 
with exit status 1.

I expect this is due to the added feature in 207 "A logic to 
automatically discover and enable home and swap partitions on GPT disks 
has been added" but it seems to cause a problem inside LXC. The problem 
goes away after downgrading to 206.

Is this a bug or should I be doing something that I am not ?
