Precreating the subvolumes won't matter, but you definitely can't use an existing subvolume for '/' mountpoint. One thing that matters a lot is that the partition scheme preset must be set to Btrfs (it is by default now). This might help or it might not :D depending on what already exists. But the key part is that you must use [+] button on the lower left when creating the / subvolume, and I also advise not specifying a size value. Just select / as the mountpoint without a size. That will create a new subvolume and assign it to /. Everything else can optionally be new or reused. https://fedoraproject.org/wiki/QA:Testcase_partitioning_custom_btrfs_preserve_home -- Chris Murphy _______________________________________________ Anaconda-devel-list mailing list Anaconda-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/anaconda-devel-list
