Subject: Fix procd not handling rapid reboot signals very well
X-Git-Url: https://git.archive.openwrt.org/?p=project%2Fprocd.git;a=commitdiff_plain;h=396a82c551ab02871ec0e6f399941c9379258bdc

Fix procd not handling rapid reboot signals very well

When keeping ctrl-alt-del pressed, or when running;
while true; do
    /sbin/reboot
done
effectively the procd shutdown cycle gets into an undefined state,
