I am storing some Unix socket files under a sub-directory beneath
$XDG_RUNTIME_DIR. On the specification, I can read:
> Files in this directory MAY be subjected to periodic clean-up. To
ensure that your files are not removed, they should have their access
time timestamp modified at least once every 6 hours of monotonic time or
the 'sticky' bit should be set on the file.
I wonder if it is necessary to set the sticky bit on each socket file in
order to avoid periodic clean-up or if it is sufficient to set the
sticky bit in the sub-directory in which I am storing all the socket files.
Thanks in advance for your help,
