User Manual Mount

[Evan]

This is a feature request, I would like the ability to be able to choose an option where user mount their own partition, as I usually made multiple subvolumes in my btrfs partition (@, @home, @var). and i mount them like this

mount -o noatime,compress=zstd,space_cache=v2,subvol=@ /dev/sdax /mnt
mkdir -p /mnt/{boot,home,var}
mount -o noatime,compress=zstd,space_cache=v2,subvol=@home /dev/sdax /mnt/home
mount -o noatime,compress=zstd,space_cache=v2,subvol=@var /dev/sdax /mnt/var
mount /dev/sdax /mnt/boot/efi
swapon /dev/sdax

with the added option of "mount from /mnt" it would be a huge time saver for me as i don't have to make multiple physical partitions on the hard drive
