I recommend learning to use LABELs on all your filesystems. They are massively
easier for humans to work with than UUIDs. You get to assign them in accordance
with how your brain functions, e.g.:
# <file system> <mount point> <type> <options> <dump> <pass>
LABEL=m12P01esp /boot/efi vfat codepage=437 0 0
LABEL=m12p02swap swap swap defaults 0 0
LABEL=m12p03usrlcl /usr/local ext4 noatime,data=ordered 0 2
LABEL=m12p04home /home ext4 noatime,acl,user_xattr,data=ordered 0 2
LABEL=m12p05stw /disks/stw ext4 noatime,acl,user_xattr,nofail 0 0
LABEL=m12p06s150 /disks/s150 ext4 noatime,acl,user_xattr,nofail 0 0
LABEL=m12p07s151 /disks/s151 ext4 noatime,acl,user_xattr,nofail 0 0
LABEL=m12p08deb10 / ext4 noatime,errors=remount-ro 0 1
LABEL=m12p09Ubionic /disks/buntu ext4 noatime,acl,user_xattr,nofail 0 0
LABEL=m12p10mint19 /disks/mint ext4 noatime,acl,user_xattr,nofail 0 0
In case you're wondering about the above naming logic, m12 is simply the last
three characters of the disk's serial number, something to reduce possibility
of label duplication when swapping disks around, or cloning.
Labeling makes output lines in blkid longer, but that enables making parsing much
easier for most human brains. Labels can be especially helpful with multiboot in
constructing custom boot stanzas much shorter and more easily parsable compared
to those generated by grub-mkconfig, e.g.:
menuentry "Debian 10 Buster" {
search --no-floppy --set=root --hint-baremetal=ahci0,gpt8 --label m12p08deb10
linux /vmlinuz root=LABEL=m12p08deb10 noresume
initrd /initrd.img
}
The exercise might even make the string /etc/fstab more memorable. :-D
