How to rebuild fstab automatically

rated 0 times [ 15] [ 0] / answers: 1 / hits: 63286 / 2 Years ago, thu, december 16, 2021, 4:34:40

I accidentally removed all the entries from the fstab files while doing a backup (Yeah, I know ;)).

I would like to know if there is a way to rebuild it with the current mount options, since I did not restart the server since the deletion. If there is no such program, could anybody help me rebuild it.

Using this, I have found the command to show the current setup, but I don't know what to do with it.

Well, I don't know of an automated way to restore it, but from your paste, created by hand..

# <file system> <mount point>   <type>  <options>       <dump>  <pass>

proc /proc proc nodev,noexec,nosuid 0  0

Please wait for a couple of other people review and approve this before you blindly copy and reboot with it, a second set of eyes is always good ;)

I've left out sdd and sr0 as they look like they're done by gvfs.
