First, some background: recently I've setup a few (too many) hard-drive
backups and new systems with LVM, lots of partitions and weird options
I'd put in the respective /etc/fstab. I don't want to write all that
shit every time I want to mount a system in /mnt/something, I wanted
«mount» to read my fstab, but although it has the «--fstab» option, it
doesn't allow me to mount anywhere but in /.
So I'm not sure if this is welcome here, but I don't really know C to
make the suggestion a patch, although it seems simple enough. Here's a
script, let's call it mount-relative:
mount -v "$1" "$2"
grep -Ev '(^#|swap|^$)' "$_mnt/etc/fstab" \
| sed -E -e 's#\s+([^\s]+)# '"$_mnt"'\1#' \
-e 's/(noauto,|,noauto|noauto)//g' \
| cat >"$_tmp"
mount -av --fstab "$_tmp"
rm -vi "$_tmp"
(Note: I'm filtering «noauto» in a dumb way because I'm lazy and it's a
As I've been using:
mount-relative /dev/something /mnt/somewhere
I think it would be useful for it to be doable with «mount» as:
mount --relative-root /dev/something /mnt/somewhere
Or at least:
mount /dev/something /mnt/somewhere
mount -a --fstab /mnt/somewhere/etc/fstab --relative /mnt/somewhere
Maybe also a «--ignore-noauto», as using «-o auto» in the script doesn't
seem to work (probably because «-o» is not made for usage with «--fstab»
In case you don't consider this a good option for mount, well, have the
script, it has been very useful to me.
