Does it require a special partition setup or would it 'just work' with existing ones?

Of course it requires special partition setup.

I have the following one:

UUID=89548d6e-b673-441e-a0d6-7abeba05c07b / btrfs defaults 0 0 UUID=6ac580e2-9c42-40dc-ac59-047f8898a41b /boot ext4 acl,user_xattr 1 2 /dev/system/home /home xfs defaults 1 2

snapshot+rollback will never work with an extra /boot partition. It's need to be part of the root filesystem. So you have to do a fresh installation and adjust your partition layout.

Thanks, good to know. Is there any documentation about how to migrate manually to a supported setup or is it just a bad idea (TM) ?

I think a fresh, clean installation is faster than moving around the data and reconfigure the system.

Faster than mount /dev/boot /mnt cp -a /mnt/* /boot update-bootloader --reinit ?? I beg to doubt it. You will need to create separate subvolumes for /boot/grub2/{i386-pc,x86_64-efi} though.

I'm not aware of any documentation.

Is default subvolume layout described anywhere? -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

Good, I'll schedule some time to do a resinstall. Thanks, Robert -- http://robert.muntea.nu/ -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

How do you have LVM-on-LUKS with a single rootfs (with /boot on the encrypted partition)?

With an extra and independent chainloader partition.

How does grub know how to boot that?

With a fixed grub.cfg pointing to the LUKS partition. Olaf -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

I dare to claim that this is rather strong statement. With separate /boot you cannot snapshot kernels and grub. Now, grub is exempt from snapshotting anyway (it is on separate volume), so you do not lose anything. And kernels are by default multiversion, so you have safety belt here as well. So with modified multiversion configuration that keeps more kernels I do not see what exact problems you have in mind. Could you elaborate, why it will never work? -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org

If my memory serves me right, it was something that was posted at least once on this mailing list by Richard Brown. Bootloaders are not my strong point, so I have not taken the time to experiment and find out whether I can work around it somehow.
