The postinst currently calls "init u", but I think that's problematic-- it would call the new binary using the new path. We can use SIGUSR1 to tell it to reopen the control channel. Maybe symlink /dev/initctl to /run/initctl and issue SIGUSR1, then issue "init u" to rexec? We would probably need a sleep between the two to give init a chance to open /run/initctl prior to issuing the "init u". Regards, Roger -- .''`.
