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

  • See the third paragraph of the section "The third field" in man fstab: "An entry swap denotes a file or partition to be used for swapping, cf. swapon(8). An entry ignore causes the line to be ignored. This is useful to show disk partitions which are currently unused. An entry none is useful for bind or move mounts." See also the previous section in man fstab, "The second field" that also mentions the use of "none". Aug 7, 2016 at 5:30
  • In case anyone's wondering, it looks like you can no longer do the same thing on Mac OS X: apple.stackexchange.com/questions/197029/… Aug 28, 2019 at 20:28

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

    Are you sure that the defaults,bind is necessary? I'm almost sure that bind would be enough. Dec 31, 2020 at 13:26

    just in case of situations on boot, i like to add nofail,x-systemd.device-timeout=2 to the options....

  • @Reishin So, it would be like this? : /source /destination none defaults,bind,nofail,x-systemd.device-timeout=2 0 0 ? Apr 13, 2022 at 21:25

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

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
