I'm a bit puzzled by Linux' (Debian) reluctance to assign a UUID
to / home. I even re-installed Debian with a smaller /home and I
have tried all the known tools for assigning a UUID to /home.
Nothing works
Which "known tools" have you tried? I believe the UUID is read-only for
a block device.
Does the laptop find your intended /home in `ls -l /dev/disk/by-uuid`?
i.e.:
ls -l /dev/disk/by-uuid/
lrwxrwxrwx 1 root root 10 2025-08-21 01:13
04ed66a1-c586-4d33-87c3-c923a7e55141 -> ../../sda2
I manually added entries in /etc/fstab with UUIDs for most devices on my
system.
In `/etc/fstab`, here's an example for my root partition (apologies for
the wrapping / formatting):
UUID=b6ed8e18-072c-43b1-baf4-66a7338327d5 / ext4
defaults,noatime,discard 0 1
Ubuntu, not Debian.
It's odd. Setting a UUID is silently ignored and blkid also ignores
the device.
The part about `blkid` ignoring the device is, indeed, odd.
I'd try booting a USB thumb drive to manually mount preferred /home on
/mnt/home to get the options and UUID (manually retrieved from
/dev/disk/by-uuid) and pay attention to any errors.
Curious to hear how you solve this - please keep us posted.
