I'm installing a system on SSD with LUKS and Btrfs, where should I enable
discard option for TRIM support? Only
/etc/fstab, everywhere, or nowhere since Btrfs detects SSDs and enables TRIM support?
I also use LVM, shoud I somehow change configs to activate TRIM support for LVM too?
P.S. I know about security implications on LUKS with TRIM and I'm fine with it.
