Hi.
I have notice some strange behaviour for tmpfs/shmfs. It seems to define the
device somehow related to the cwd where the mount command is issued.
I will explain. This is the relevant part of my /etc/fstab:
tmpfs /dev/shm tmpfs defaults,size=128M 0 0
And now I try to mount it:
werewolf:~# df

/dev/sda1 248895 79908 156137 34% /

/tmp/tmpfs 131072 0 131072 0% /dev/shm
???? Strange devices.... both mounted under /dev/shm.
BTW, look at /etc/mtab:
werewolf:/tmp# cat /etc/mtab
/dev/sda1 / ext2 rw 0 0
/procfs /proc proc rw 0 0
^
devpts /dev/pts devpts rw,mode=0620 0 0
/dev/sda2 /usr ext2 rw 0 0
/dev/sda3 /home ext2 rw 0 0
/dev/sda5 /toast ext2 rw 0 0
/dev/sdb1 /mnt/disk reiserfs rw 0 0
/root/tmpfs /dev/shm tmpfs rw,size=128M 0 0
^^^^^^^^^^^
/tmp/tmpfs /dev/shm tmpfs rw,size=128M 0 0
^^^^^^^^^^
Why devpts is just plain 'devpts', and procfs is '/procfs' ??? Some bug
that generates device name with cwd for all special filesystems but devpts ?
Kernel or mount bug ?
TIA

Mmm, mine is mount-2.11e on 2.4.7 final, SMP box.
perhaps mount bug ?
Going to get the new one...

I don't have any problems... mount version is 2.11g on 2.4.7
Uni-Processor and 2.4.7-pre3 SMP.

Right, mount bug. Version 2.11h works fine...

This means an update to the Changes documentation. It lists 2.10o as
the minimum.
