Thanks to forum and especially @eugen-b I know a lot about btrfs.
I would like to ask about one more.
I feel that I can’t be wrong.
If I have btrfs formatted partition. Let’s call it sda1
On this partition I have 2 subvolumes
@ for /
@home for /home
Fstab configured to boot from @
Can I in RUNNING system mount sda1 in /mnt with subvolud=5
So in mnt I’ll have @ and @home subvolumes visible
Then create snapshot of @ and @home
Let’s say @_bak @home_bak
Do some things with the system
For example install Firefox and its configuration
Then mount sda1 in mnt again
Do btrfs subvolume delete for @ and for @home
Then do snapshots of @_bak and @home_bak
With original names so @ and @home
Can I do something like this on running system ?
Will this revert all changes made to @ and @home ?
If it’s not possible then can I just run live system and mount my hard disk inside and then do the btrfs operations ?
