> Can you explain more? Is it to preserve the file between reboots?

/var/run is the right place to store socket files according to the current Filesystem Hierarchy Standard:
http://refspecs.linuxfoundation.org/FHS_2.3/fhs-2.3.html#VARRUNRUNTIMEVARIABLEDATA
It is also recommended by others: http://stackoverflow.com/questions/7580346/where-to-place-unix-domain-af-unix-sockets-end-points-files

But after testing the patch, I discovered that /var/run is not writable by non-root. So this won't work for Audacity which is launched by any user.

The socket file won't be preserved between reboots. Only data in /var/tmp would be preserved.

Every Linux distro should have /var/run (at least if they want to comply with the FHS).
