I'm having trouble finding an answer for this question

Does mount --bind persist over reboot?

On my CentOS it looks like it doesn't, so I've placed apropriate mount --bind calls in rc.local.

How can I do mount --bind to avoid rc.local scenario?

    Why would you think a mount --bind would be any different than any other mount? – andol May 13 '10 at 14:25

Create an entry for the bound mount in your /etc/fstab. An example is below.

/path/to/source/dir /path/to/mount/point none bind 0 0

  • What do the "none" and 0 0 do? – raphael75 Aug 23 '18 at 19:09

    "none" represents the file system and "0 0" provide configuration used by dump and fsck, respectively. Since this is an existing path and not a unique disk/file system, empty or disabled values are specified for these fields. – nabrond Sep 23 '18 at 12:40
  • are source dir and mount point arguments in the same order as for the mount command? – John Bachir Sep 5 '19 at 15:45
  • @JohnBachir yes, same order – Mugen Mar 31 '20 at 11:36

You should add the appropriate info into /etc/fstab in order to mount the filesystem at boot.
