Re: [PLUG] Fixing /boot/ too small

["Rich Mingin \(PLUG\) via plug" <plug@lists.phillylinux.org>]

FWIW, I switched from UUID to label, because UUID changes any time you remake a filesystem or format, while labels can be persisted.

Not terribly relevant to your current situation, since you'd be moving your boot files from one partition label to another as well.

They are old, it's BIOS and MBR, but UUIDs are in use in /etc/fstab.
And everything Just Works now, the only thing I need to do is move
'/boot/' from its own md device into '/' so there is space.


`/etc/fstab` excerpt (updated to but not rebooted):
```
# / was on /dev/md2 during installation
UUID=bafdc515-511e-44b9-85d0-e1cd164cc58c /               ext4
errors=remount-ro 0       1

# /boot was on /dev/md1 during installation
#UUID=21fd376b-fa9a-4dd0-bfa3-f3ca314d0648 /boot           ext4
defaults        0       2
# 2020-04-07 /boot/ HACK
UUID=21fd376b-fa9a-4dd0-bfa3-f3ca314d0648 /boot.old        ext4
defaults        0       2
```

And (edited for clarity):
```
