X-Git-Url: http://git.openwrt.org/%22http:/oss.oetiker.ch/rrdtool//%22/%22http:/oss.oetiker.ch/rrdtool/%22?a=commitdiff_plain;h=59d22013f9dd38f60b0f953534601532dd429c28;p=project%2Fprocd.git

jail: make udebug socket optional

Do not fail the jail mount if it does not exist, since udebugd is
optional.
