Subject: tmpfs in 2.4.3 and AC

Hi,

tmpfs (or shmfs or whatever name you like) is still different in official
series (2.4.3) and in ac series. Its a kick in the ass for multiboot,
as offcial 2.4.3 does not recognise 'tmpfs' in fstab:

shmfs /dev/shm tmpfs ...

Any reason, or is because it has been forgotten ?

Use type shm. It works in both versions.

Alan picked up the tmpfs extensions. Linus didn't.

There is no tmpfs in vanilla 2.4.3 kernel.

I use this start script to mount tmp/shmfs:

#!/bin/sh

[ -d /dev/shm ] || mkdir -p /dev/shm

shmfs_avail=$(grep -qci 'shmfs' /proc/filesystems || true)
tmpfs_avail=$(grep -qci 'tmpfs' /proc/filesystems || true)
devshm_mounted=$(grep -qci '/dev/shm' /proc/mounts || true)

[ $devshm_mounted = 0 ] || exit 0

if [ $shmfs_avail = 1 ]
then
echo -ne "Mounting shmfs: "
mount none /dev/shm -t shmfs && echo "ok."
exit 0
fi

if [ $tmpfs_avail = 1 ]
then
echo -ne "Mounting tmpfs: "
mount tmpfs /dev/shm -t tmpfs && echo "ok."
fi
