I'm trying to setup my external harddrive to mount automatically on startup, following Akshit's terminal guide.
I initially used the PARTUUID in `/etc/fastab' instead of the UUID:
UUID=191486e0-6049-46aa-973c-425d317b629a /mnt/nas exfat uid=1000,gid=1000,umask=0022,auto,rw 0 0
This gave me an error when I ran findmnt --verify --verbose at which point I rechecked blkid and noticed that I'd been using the partition ID:
/dev/sdb1: LABEL="My Book" UUID="20C9-C659" TYPE="exfat" PTTYPE="atari" PARTLABEL="My Book" PARTUUID="191486e0-6049-46aa-973c-425d317b629a"
So I've added the actual UUID in fstab, but now I'm not sure if I should be using that or if I should be using the PARTUUID, and why my UUID is so much shorter than other examples that I've seen (especially when a "UUID is guaranteed to be unique. As far as I know, collisions will not happen within the lifetime of the universe").
