Description Vishnu Ganth 2015-04-30 14:28:28 UTC

Description of problem:
The name of the overlay filesystem changed from overlayfs to overlay at some point. Support for this was added in commit 38b3491 - https://github.com/lxc/lxc/commit/38b34913fad2a4bcc842c2c377c0cb7bb90abe0f, which was made after the release of lxc 1.0.7. It looks like this change should be available in LXC releases 1.1.1 and later.

Since Centos - 7.1 kernel is not compatible with LXC - 1.1.1, need to integrate this fix to the LXC 1.0.7 rpm in EPEL repository.

Comment 4 Thomas Moschny 2015-10-24 18:34:32 UTC

This is actually upstream commit 388db0d9 (on the stable-1.0) branch, and will be in 1.0.8.

However, as there is a pending security update, I think I'll include the fix.
