[Bug 79620] Re: gdm's socket in /tmp is deleted by bootclean

[Daniel J Blueman]

Just to state my reasoning for thinking it is a GDM bug:

gdm creates a file in /tmp/.gdm_socket, but /tmp has the sticky bit set,
meaning that anyone else can delete other people's files, not possible
without the sticky bit set.

/var/run is used for other programs to create sockets, and according to
the Linux File Hierarchy Standard, is the correct place:

http://www.pathname.com/fhs/pub/fhs-2.3.html#VARRUNRUNTIMEVARIABLEDATA

This would entirly justify the (acceptable) behaviour of the bootclean
script, run from wherever and whenever in the boot process. FHS exists
to prevent these classes of races/design bugs from occuring.

Comments/suggestions? What arguments are against having the socket in
/var/run?
