Description Walter 2013-10-31 01:11:58 UTC

I just built a new LXC container using lxc-gentoo and received an error starting up due to lack of CAP_SYSLOG.

Since CAP_SYSLOG makes little sense to provide to many containers, it might be worth detecting a lack of CAP_SYSLOG before attempting to run the dmesg portion of the init scripts or outright disabling any attempts to read dmesg when running under LXC.

Log follows...

INIT: version 2.88 booting

   OpenRC 0.11.8 is starting up Gentoo Linux (x86_64) [LXC]

dmesg: read kernel buffer failed: Operation not permitted

Doesn't occur on recent builds. Can now be ignored.
