Subject: selinux: Check access vector for enable/disable perm for each unit file
X-Git-Tag: v209~607
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?a=commitdiff_plain;h=4f7385fa496242f06aaf358b66b28d71348607b3;p=elogind.git

selinux: Check access vector for enable/disable perm for each unit file

SELinux check will be done using the context of the unit file as as a
target instead of the default init_t context, allowing selinux control
on the level of individual units.
