I'm trying to add
mount --bind /proc/ /chroot/mysql/proc to
/etc/fstab. How can I do this?
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 ;)
nofailignores 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
nofail in fstab from Linux & Unix SE
