Comment 7 for bug 2060624

I've NOT encountered this issue with a install.alongside (calamares/lubuntu) or the ubuntu-desktop-installer equivalent (auto(resize) testcase)... as both installs (prior + new) appear in GRUB on second install when that is run. This is where it matters most anyway, and it works perfectly.

I've only encountered this on manual.partitioning (something-else equivalent) and manually selecting a pre-existing partition for re-use (ubuntu-desktop-install now marks that as with format compulsory)...

This will impact very few users.. and can easily be covered by a RELEASE NOTES message if required anyway, as very few users will be impacted by it (most will have no issue dealing with the PROBER edit)..

Alas the Xubuntu install no longer exists; that install being overwritten by subsequent QA test installs. I'd have to re-create the issue, which won't be tonight...
