That's weak, so I will try again.
I haven't been able to reconcile the Wiki with all the other docs out there, including other Gentoo docs. I finished up with this: # parted -l /dev/nvme0n1 Model: Unknown (unknown) Disk /dev/nvme0n1: 256GB Sector size (logical/physical): 512B/512B Partition Table: gpt Disk Flags: Number Start End Size File system Name Flags 1 1049kB 3146kB 2097kB uefi bios_grub 2 3146kB 2147MB 2144MB fat32 boot boot, esp 3 2147MB 4295MB 2147MB linux-swap(v1) swap 4 4295MB 19.3GB 15.0GB ext4 rescuesys 5 19.3GB 36.5GB 17.2GB ext4 gentooroot --->8 > man mount shows that discard/TRIM is supported by linux vfat driver, as > vfat also supports all the fat mount options. I've found that fstrim only works on my VFAT /boot if it's been mounted during boot. If it's set to noauto in fstab, and then mounted with -odiscard, fstrim complains that "discard is not supported" -- Regards, Peter.
