How do I do 'mount --bind' in /etc/fstab?

Question

I'm trying to add mount --bind /proc/ /chroot/mysql/proc to /etc/fstab. How can I do this?

Answer 1

The mount command accepts --bind or -o bind.

In the /etc/fstab file, you can use the following line:

/source /destination none defaults,bind 0 0

Answer 2

If I had a volume mounted at /media/3tb-vol1/Private/, and I wanted to bind it to /srv/Private I have a /etc/fstab like this.

/media/3tb-vol1/Private/ /srv/Private        none    bind

Answer 3

In Addition to rely on an always existing drive, if you would use this entry to mount an external drive, the boot would fail while the drive is not connected.

In Addtion to the solve this, there is a known boot options for this ;)

• nofail ignores non existing mount points and continues regardless

/media/3tb-vol1/Private/ /srv/Private        none    bind,nofail

i would also suggest to see this as Reference What is the difference between nobootwait and nofail in fstab from Linux & Unix SE

Answer 4

The mount command accepts --bind or -o bind.

You have /path/other/usr and you want that will be /usr

In the /etc/fstab file, you can use the following line:

/usr      /path/other/usr    none    defaults,bind    0 0
