This gives me weird output for df:

This is fstab:
/dev/sda1 / ext4 acl,relatime 1 1
none /proc proc defaults 0 0
/dev/sda2 /opt ext4 acl,relatime 1 2
/dev/sda3 swap swap defaults 0 0

/home/shared/media/video /export/video bind bind 0 0
/home/shared/in /export/in bind bind 0 0
/opt/soft /export/soft bind bind 0 0
All bind mounts are duplicated !
They are mounted twice:
werewolf:/etc> grep music /proc/mounts
/dev/sdc1 /home/shared/media/music ext4
rw,relatime,user_xattr,acl,barrier=1,data=ordered 0 0
/dev/sdc1 /export/music ext4 rw,relatime,user_xattr,acl,barrier=1,data=ordered
0 0
/dev/sdc1 /export/music ext4 rw,relatime,user_xattr,acl,barrier=1,data=ordered
0 0
An also df from coreutils should be taught to ignore more special filesystems,
or not
Note that df documentation says to use the option -a to list "dummy file
systems".
Which includes the binds. Otherwise binds aren't displayed (with mga1).
What happens if you use
df --total
Does it give the real totals of mounted devices ?
or include the dummy file systems ?
and also the duplication ?
On mga1, with
df -a --total
the total includes all lines displayed. (including binds, tmpfs, etc.)
(Also /proc is displayed.)
Without -a, only real partitions are displayed.
