[pbs-devel] applied: [PATCH backup] d/postinst: fixup userid for older termproxy tasks

[Thomas Lamprecht]

At the time when we can fix this up the new (and possibly an old)
server daemon process is running, so use the flock CLI tool from
util-linux to ensure we do the same locking as the server and thus we
avoid a race condition.
