I am trying to reroot to a ggate device something like:
root@:~ # ggatec create -o rw 192.168.3.11 /tmp/omega2-ggate-fs.img
root@:~ # kenv vfs.root.mountfrom=ufs:/dev/ggate0
root@:~ # reboot -r
May 13 20:02:59 reroot: rerooted by root
Writing entropy file:.
Writing early boot entropy file:/etc/rc.shutdown: WARNING: write
failed (read-only fs?)
Trying to mount root from ufs:/dev/ggate0 ...
Obviously this doesnt work as init kills the ggate0 devices backend
ggatec process when rerooting.
In init.c for reroot:
error = kill(-1, SIGKILL);
From kill (2) man page:
If pid is -1:
If the user has super-user privileges, the signal is sent
processes excluding system processes (with P_SYSTEM flag
Is it possible to set a userland programs p_flag to P_SYSTEM somehow?
Or is it possible/sensible to edit init to accept a pid as an argument
not to kill when rerooting?
Or is this just not feasible without hacking init as in this
