Subject: [PATCH] ci(installer-iso): /tmp not /var for livemedia resultdir
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

/var/lmc-out-PID kept being marked 'exists' by livemedia even after
rm -rf. Probably bind-mount or tmpfs from runner persists /var.
Switch to /tmp/lmc-out-PID — act job container's /tmp is fresh per
run.
