Yes. > Any ideas, when does it becomes read-write? That would be when / is remounted in /etc/rcS.d/S06checkroot.sh, and mount_shm() is first called earlier in /etc/rcS.d/S03mountdevsubfs.sh; it seems that /etc/rcS.d/S11mountall.sh calls again mount_shm() and stuff afterwards, but at that point something was already mounted on /dev/shm the first time because the migration failed, so it's too late. At least that's for the /dev/shm -> /run/shm direction. For /run/shm -> /dev/shm, recreating the /dev/shm directory would fail at first but I suspect it would succeed in the second call. -- Pierre Ynard
