It's rather confusing that gdisk (my preferred partitioner, which
I use outside the installer) refers to the PARTLABEL as the
partition's name rather than label:
Command (? for help): c
Using 1
Enter name: Kirk01
Command (? for help): i
Using 1
Partition GUID code: 0FC63DAF-8483-4772-8E79-3D69D8477DE4 (Linux filesystem)
Partition unique GUID: 13005F6E-6289-4AB9-B36E-8689CF983EF5
First sector: 2048 (at 1024.0 KiB)
Last sector: 2930277134 (at 1.4 TiB)
Partition size: 2930275087 sectors (1.4 TiB)
Attribute flags: 0000000000000000
Partition name: 'Kirk01'
and the symlinks¹ are:
S:disk/by-partuuid/13005f6e-6289-4ab9-b36e-8689cf983ef5
S:disk/by-path/pci-0000:00:1d.7-usb-0:5:1.0-scsi-0:0:0:0-part1
S:disk/by-partlabel/Kirk01
S:disk/by-id/wwn-0x5000c5001a769150-part1
S:disk/by-id/ata-ST31500341AS_9VS3AMF3-part1
S:disk/by-uuid/beca0527-b041-4597-a585-9356f32b63a7
I'm too old to type UUIDs except by copy/paste or by completion,
and they make my head spin, so I try to use LABELs and PARTLABELs
wherever possible. It's always been a disappointment that Grub
can't write LABELs automatically in grub.cfg, so I have a little
script that translates the UUIDs into LABELs using the information
in /run/udev/data/b8:* (b259:* for my SSD). I have to rerun it
after kernel and Grub upgrades.
¹ I have a suspicion that the system is tardier about updating
the PARTLABEL symlinks than some of the others, after you
change them with the {f,g,sg}disk program. But it's only a
hunch: where it matters (ie the actual system disk), I reboot.
Cheers,
David.
