[OpenWrt-Devel] [PATCH procd] Add ctrlaltdel handler to procd

[Michel Stam]

Procd, up until now, did not support the ctrlaltdel handler. Thus,
the system would immediately reboot upon the three-finger salute,
and no shutdown scripts would be run. This patch adds the handler
for the /etc/inittab entry, so that /sbin/reboot can be run and
in turn the shutdown scripts can be invoked.
