So after your troubles with upgrade, you try fresh install. Understandable. Do you have a backup of your old system?
I do not use LVM. When I boot the Leap 15 DVD and try to set up partitions, I get 6 rather that the usual 3 generated under 14.3. For some reason, that I can probably research on google, it sets up partition 1 as a BIOS boot partition. Not sure why this is required.
Not always, but I think it is now always created if the disk is partitioned with GPT - probably all new disks are now using GPT. And all new computers have UEFI, which is designed to work with GPT (of course, Legacy MBR is supported). So YaST defaults to create that partition. Better do it than fail because does not exist. And better now than cry later because there is no space for it. Anyway, that partition is really tiny, about 8 MB. It doesn't matter, just let it be even if unused.
But then it sets up partitions 2 and 3 as BtrFS partitions, then partition 5 as another BtrFS partition mounted as root. Then partitions for the usual swap and home file systems.
Why are there 3 BtrFS partitions? The only comment I can find, all the way in Release notes:7 technical, is that there is a single subvolume for all of /var.
Ok, probably it is only a single btrfs partition with several subvolumes. It has to be done that way because some directories need different settings; there is not a single setting that applies fine to all directories. Things like do snapshots to this one but not to this other. And there are less now than before, because the rpm data has been moved off /var.
I changed the root file system type to xfs and was able to generate the 3, (4 with BIOS boot), partition layout I am familiar with.
"/" on XFS with no boot partition? Last time I tried that I failed, but maybe it works on GPT plus bios partition. I'll have to consider that. My personal choice is ext4 for "/", XFS for home, since many years. Before it was ext3, before it was reiserfs.
Comments please.
All good. However... you do not preserve your old /home? Or is it a new disk? -- Cheers / Saludos, Carlos E. R. (from 42.3 x86_64 "Malachite" at Telcontar)
