Hi,
I've been running with the fstrim.timer for years and recently noticed
that my ESP partition always reports the same amount for trimmed blocks
(512MB). It appears fstrim doesn't support FAT32 filesystems?
FAT supports discards since kernel ~4.19.
fstrim doesn't have file system specific support, it directly calls
FITRIM() ioctl and the kernel handles the file system specifics.
Should I
use the "discard" option in fstab for /boot/efi ?
I know it's not a big issue since we seldom write the ESP after
installation except for /boot/efi/EFI/fedora/grubenv after updates (or
perhaps shim updates) but I'm wondering...
Yeah I don't think you need to consider it too much.
