How do I mount the contents of /home/multimedia in two places under Linux operating systems?
If you are using Linux kernel v2.4.0+, you can remount part of the file hierarchy somewhere else using the following mount command syntax. This is useful for NFS servers in /exports. You must type the following commands as the root user. The syntax is
mount --bind /path/to/olddir /path/to/newdir mount -B olddir newdir |
The syntax for /etc/fstab entry is:
/olddir /newdir none bind |
In this example, mount /home/multimedia/mp3 and /home/multimedia/videos as follows:
# mkdir -p /exports/{music,videos}
# mount --bind /home/multimedia/mp3 /exports/music
# mount --bind /home/multimedia/videos /exports/videos
Verify new settings:
# mount
# df -a
# mount | egrep -i --color 'music|videos'
Update /etc/fstabe file as follows:
# vi /etc/fstab
Append the following:
/home/multimedia/mp3 /exports/music none bind /home/multimedia/videos /exports/videos |
Save and close the file.

Thanks ! Very useful for restricted chrooted account too.
I’ve set up an sftp chrooted account and wanted to share a sub-directory from outside of the root :)
Wonderful now.
You can also add this :
# mount –bind /mnt/sourcedir targetdir
# mount -o remount,ro targetdir
To have a read-only access :)
Thanks :)
