Public bug reported:
In hardy heron, a fuse based sshfs mount that is mounted through
/etc/fstab does NOT match its corresponding entry in /etc/mtab.
I am filing this as a bug, because it breaks a number of standard
ubuntu/gnome/debian/linux utilities, including umount and the unmount
capability of the "Disk Mounter" applet.
For example, this line in /etc/fstab:
[EMAIL PROTECTED]:/home/username
/home/username/mnt/sshfs/ubuntusshserver/username fuse
comment=sshfs,users,exec,nodev,nosuid,rw,nosuid,noauto,uid=1000,gid=1000,allow_other,reconnect,transform_symlinks,port=22,BatchMode=yes
0 0[/Code]
results in this line in /etc/mtab (when this mount point is mounted):
[EMAIL PROTECTED]:/home/username
/home/username/mnt/sshfs/ubuntusshserver/username fuse.sshfs
rw,nosuid,nodev,max_read=65536,allow_other,user=username 0 0[/Code]
The line mentioned for /etc/fstab allows me to easily mount the sshfs
mount point from mount or the "Disk Mounter" applet with no problems,
but breaks umount and "Disk Mounter" for unmounting. "fusermount -u" or
"fusermount -u -z" still work.
Running the following line to use sed to edit /etc/mtab to correct the problem
after a mount results in desired behavior, and verifies that this problem is a
bug:
[Code]sudo sed 's/\([EMAIL PROTECTED],[EMAIL PROTECTED])\(.\{1,\}\) fuse\.sshfs
/sshfs#\1\2 fuse /' -i /etc/mtab[/Code] This line is, of course, a workaround
for the bug, and requires su privileges to run, so it is NOT a solution.
The source package for this bug should be sshfs-fuse 1.9-1. The binary
package is sshfs. I believe that this behavior did not exist in fiesty
fawn, and cannot tell you if it existed in gutsy gibbon. I am almost
sure that this is new to hardy heron, so it is probably a design change
that resulted in some bugs. I also believe that this bug is the true
cause of bug#152978 (see
