I have read the snapper documentation and also that for using Yast 2 to set boot loader options but I have not been able to find out how to do this.
As far as I am aware my installation is a new one with btrfs and incudes snapper with default configuration which the documents tell me should include this capability. Not in my installation it seems. Please could somebody help me figure this out and enable the Start Bootloader from a read-only snapshot option…

Hi and thanks for the reply. I think this is what you need:-

Hi Budge,
GRUB is not to blame: SUSE_BTRFS_SNAPSHOT_BOOTING="true"
But you don’t have the hidden folder /.snapshots. If it isn’t there, snapper can’t write the snapshots. You may also check
btrfs subvolume list -t /
Here is mine:
pluto:~ # btrfs subvolume list -t /
ID gen top level path

The snapshots should be in their own subvolume. If ithat doesn’t exist I think something went wrong during your initial installation. AFAIK this can’t be corrected unless by a fresh install. But others may know better.
Yes, as was pointed out, /.snapshots is missing. Show output of
btrfs subvolume list /
Thanks, here is result:-

Not what I expected as there is no @/.snapshots showing. Before I reboot is my /etc/fstab now correct?
My bad, here is /etc/fstab now:-

Hope this is right but I still have something wrong:-
alastair@HP-Z640-1:~> sudo mount -a
mount: @/.snapshots: mount point does not exist.
alastair@HP-Z640-1:~>
I said /.snapshots mount point, not @/.snapshots.
Yes, I was right first time but it wasn’t working and thought I had misread your post. I had reverted it as soon as I saw the mount problem. Here is my /etc/fstab:-

When I check by trying to mount the /.snapshot I have :-

mount: /: /dev/nvme0n1p4 already mounted on /.
alastair@HP-Z640-1:~>
As all looked OK I tried re-booting but I still do not have the list as required.Show
ls -l /.snapshots
ls -l /.snapshots/*/*.cfg
snapper list
Ok as requested:-

That is the reason why no snapshots are offered at boot time. Menu entry for each snapshot is created statically when snapshot itself is created. If they are missing, nothing is shown. Try creating new snapshot now, when /.snapshots is mounted. Do you see this new snapshot in grub menu?
Hi arvidjaar, I have created a snapshopt and can see it listed:-
alastair@HP-Z640-1:~> sudo snapper create --description 'Test_snapshot'

Should I reboot to see if it is in the grub menu or where else can I look for it? It is not where you last suggested I look:-
alastair@HP-Z640-1:~> sudo ls -l /.snapshots/*/*.cfg
ls: cannot access '/.snapshots/*/*.cfg': No such file or directory
alastair@HP-Z640-1:~>
You could look in /.snapshots/grub-snapshot.cfg whether it had line referring to the new snapshot. But at the end you want it in the grub menu, so this is the ultimate check.
OK, I have looked at the ./snapshots/grub-snapshot.cfg and it is not as expected but my test was numbered 164 and reference to it is listed:-

I am puzzled by the earlier command:-

[sudo] password for root:
ls: cannot access '/.snapshots/*/*.cfg': No such file or directory
alastair@HP-Z640-1:~>
I had used sudo before as suggested but if I log in as root the command works OK. Usually if sudo does not work I get an error message but this time the message is different as I only get cannot access, which on reflection, comes to the same thing. Logging in as root I get the expected result:-
