Subject: 2.4.7 tmpfs strange behaviour
Date: Wed, 25 Jul 2001 00:59:40 +0200 [thread overview]
Message-ID: <20010725005940.A5607@werewolf.able.es> (raw)
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
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/sda1 248895 79908 156137 34% /
/dev/sda2 3099292 2080088 861768 71% /usr
/dev/sda3 4095488 1591936 2295512 41% /home
/dev/sda5 1027768 4 975556 1% /toast
/dev/sdb1 4232960 32840 4200120 1% /mnt/disk
werewolf:~# mount -a -t tmpfs
werewolf:~# df

/dev/sda3 4095488 1591936 2295512 41% /home
/dev/sda5 1027768 4 975556 1% /toast

/root/tmpfs 131072 0 131072 0% /dev/shm
werewolf:~# cd /tmp
werewolf:/tmp# mount -a -t tmpfs
werewolf:/tmp# df
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/sda1 248895 79908 156137 34% /

/dev/sda3 4095488 1591936 2295512 41% /home
/dev/sda5 1027768 4 975556 1% /toast
/dev/sdb1 4232960 32840 4200120 1% /mnt/disk
/root/tmpfs 131072 0 131072 0% /dev/shm
/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
