Subject: lxc-init: continue even if we fail to mount /dev/mqueue
X-Git-Tag: lxc-1.0.0.alpha1~1^2~155
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=5d4d3ebb13705d1e102429c75fc06932f81816dd;p=thirdparty%2Flxc.git

lxc-init: continue even if we fail to mount /dev/mqueue

The 'lxc-init' (a lightweight init process used by lxc-execute in place
of upstart etc) tries to mount /dev/mqueue during startup. If that fails
(for instance due to missing support for mqueue in kernel) then it
aborts execution and returns -1. This is unreasonable as very few
applications actually need /dev/mqueue.

This similar to what we do with /dev/shm.
