No /dev in /etc/mtab
Last modified: 2005-09-06 16:17:20 UTC
There is no entry for /dev in /etc/mtab, so df cannot learn about that mount point.
/dev is part of the root file system and udev is used to update missing entries in this directory.
/dev is a mount point.
Not on standard SuSE Linux 10 nor 9.3
What are you smoking????
Nothing. AFAIK a static initramfsdevs partition is not what we do. This was the result of the dist team meeting. Hannes?
Yes, we have /dev a mount point in 10.0. Been there since Preview2. Yes, /dev does not show up in /etc/mtab as it's being mount prior to accessing the root fs and hence prior to creating /etc/mtab. Should it show up there? Andreas, what's your opinion
Please ask on research. I personally think it should show up there.
Ruediger, this needs to be changed in aaa_base:/etc/sysconfig/boot.localfs: --- boot.localfs.orig 2005-09-05 16:56:50.000000000 +0200 +++ boot.localfs 2005-09-05 17:06:31.000000000 +0200 @@ -19,7 +19,7 @@ # to get max number of parallel fsck processes . /etc/sysconfig/boot - +. /etc/sysconfig/kernel if [ -f /etc/sysconfig/dump ]; then . /etc/sysconfig/dump fi @@ -132,7 +132,11 @@ case "$1" in echo "Mounting local file systems..." mount -fv -t proc proc /proc mount -fv -t sysfs sysfs /sys - mount -fv -t tmpfs tmpfs /dev/shm + if [ -n "$DEV_ON_TMPFS" -a "$DEV_ON_TMPFS" != "yes" ] ; then + mount -fv -t tmpfs tmpfs /dev/shm + else + mount -fv -t tmpfs initramdevs /dev + fi rc_status optpts="-o mode=0620,gid=5" mount -fv -t devpts $optpts devpts /dev/pts Can you do it, please?
Are you sure you want to drop the /dev/shm mount? What happens with the old /dev contents when another tmpfs is mounted on top of it?
well, what about just listing both, /dev and /dev/shm.
Hannes, ok ?
Personally, I don't care. I just found it a bit pointless to mount a tmpfs /dev/shm on a tmpfs /dev. But we might as well list both so as not confuse users. Having said that; no-one is ever going to umount /dev/shm, or is he?
You are of course right, I was pretty confused.
On the other hand, /etc/mtab should list all current mount points, so /dev/shm should be added as well.
True. So _if_ /dev/shm is mounted it should be listed there. Only I'm not quite sure that we actually do mount it. initramfs certainly doesn't when using dev on tmpfs (not much point, really). Don't know about aaa_base. Ruediger?
See /etc/init.d/boot.shm. Also note that /dev/shm is mounted with a different size (which is configurable) than /dev.
