Subject: fix /dev/shm permissions
X-Git-Url: https://git.librecmc.org/?a=commitdiff_plain;h=acb157e638aa93490ca84be381c28643d50d4e4a;p=oweals%2Fprocd.git

fix /dev/shm permissions

On my Ubuntu system, the permissions are 1777. They are incorrect in
procd, leading to this:

This in intended for both CC and DD.
