I've come to the conclusion that there is no good way to return to the initramfs at all after init moves to the real root device. What I have found is that the only way is for another process to keep a cwd or open file handle on the initramfs which plays very badly with killall.
Anybody got a way to make a user process other than init involunerable to kill -9? <g>
It would be dirt-simple if I could mount --rbind / /root/initrd where / is the initramfs and /root is a mounted filesystem, but that creates cycles and so breaks other things.
Oh, and mount / followed by ls / returns the contents of the initramfs. Weird. umount -l / has the exteremely bizarre effect of leaving the process stranded in / unless it currently has pwd or open directory handle elsewhere.
Anybody want a patch that dumps the executor of umount / in the initramfs, then does a lazy unmount? That, however, carries risks of its own so might not be the best move. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
