procd: update to git HEAD and add new script helpers
e10de28 jail: cgroups-bpf: fix compile with musl 1.2 f5d9b14 hotplug-dispatch: fix rare memory leaks in error paths Add new init script helpers: procd_add_start_mount_trigger procd_add_reload_mount_trigger procd_get_mountpoints Both trigger helpers expect a list of paths which are checked against the mount targets configured in /etc/config/fstab and a trigger for all mountpoints covered by the list of paths is setup. procd_get_mountpoints is useful to find out if and which mountpoints are covered by a list of paths. Example: DATADIRS="/mnt/data/foo /mnt/data/bar /etc/foo/baz /var/lib/doe" start_service() { [ "$_BOOT" = "1" ] && [ "$(procd_get_mountpoints $DATADIRS)" ] && return 0 procd_open_instance # ... procd_close_instance } boot() { _BOOT=1 start } service_triggers() { procd_add_start_mount_trigger $DATADIRS } Signed-off-by: Daniel Golle <daniel@makrotopia.org>
