Subject: [PATCH] docs: clarify sockdir's separation
|
|
|
|
There's another reason for separating sockdir from tmpdir, beyond "shorter
|
|
pathnames needed": permissions. For example, passt drops privileges such
|
|
that it cannot access "/tmp", and that restricts both the unix domain
|
|
socket and the PID file of passt.
|

This is different from C<guestfs_get_tmpdir>, as we need shorter
|
|
paths for sockets (due to the limited buffers of filenames for UNIX
|
|
sockets), and C<guestfs_get_tmpdir> may be too long for them.

The environment variable C<XDG_RUNTIME_DIR> controls the default
|
|
value: If C<XDG_RUNTIME_DIR> is set, then that is the default.
