[pkg-lxc-devel] Bug#1119654: lxc-start --define lxc.mount.entry doesn't seem to work anymore on loong64

[Paul Gevers]

Package: lxc
Version: 1:6.0.5-1
Severity: normal
File: /usr/bin/lxc-start
X-Debbugs-CC: debian-ci at lists.debian.org

Hi,

It seems that since very recently, the lxc containers for ci.debian.net 
on loong64 (sid) don't mount the shared directory anymore that 
autopkgtest needs and configures.

loongson at ci-worker-loong64-01:~$ sudo lxc-start --name elbrus --daemon 
--define "lxc.mount.entry=/tmp/autopkgtest-lxc.xn_rqv6m 
tmp/autopkgtest-lxc.xn_rqv6m none bind,create=dir 0 0"
loongson at ci-worker-loong64-01:~$ sudo lxc-attach elbrus
root at elbrus:/# ls -al /tmp
total 0
drwxrwxrwt  6 root root 120 Oct 29 21:29 .
drwxr-xr-x 18 root root 440 Oct 29 21:29 ..
drwxrwxrwt  2 root root  40 Oct 29 21:29 .font-unix
drwxrwxrwt  2 root root  40 Oct 29 21:29 .ICE-unix
drwxrwxrwt  2 root root  40 Oct 29 21:29 .X11-unix
drwxrwxrwt  2 root root  40 Oct 29 21:29 .XIM-unix

I ran the same lxc-start command once with lxc.log.level=0, this is the 
output:
