Anaconda requires a new subvolume for / but doesn't require a reformat. The Custom UI shows the / mountpoint's reformat checkbox grayed out and checked, which might give the impression that whole partition will be reformatted. It's confusing but just a cosmetic UI anomaly. There is a way to do this with kickstart, btrfs --mkfsoptions https://pykickstart.readthedocs.io/en/latest/kickstart-docs.html#btrfs -- Chris Murphy _______________________________________________ Anaconda-devel-list mailing list Anaconda-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/anaconda-devel-list
