Quote from https://wiki.gentoo.org/wiki/Handbook:AMD64/Installation/System#Partition_labels_and_UUIDs: " To improve performance, most users would want to add the noatime mount option, which results in a faster system since access times aren't registered (those are not needed generally anyway). This is also recommended for solid state drive (SSD) users, who should also enable the discard mount option (ext4 and btrfs only for now) which makes the TRIM command work. " But according to this table - not only ext4 and btrfs https://wiki.archlinux.org/title/Solid_state_drive#TRIM Related issue about discard https://bugs.gentoo.org/608310. Or please give me permission to edit the Handbook.
