[gentoo-user] lxc filling /dev

[William Kenworthy]

What would cause an lxc instance to leak memory filling /dev?  Of
course, when it gets to 100% things ... stop! - but only for that lxc
instance.

The host is an odroid N2 with a gentoo-sources kernel and a gentoo arm
(aarch64) userland running 6 gentoo based lxc instances.

du and ls -al do not give any clues, the host /dev is normal and all
running lxc instances do it, but at different rates
