Looks like UsrMove fixed the problem with separate /usr volume. This is the layout I tested: UUID=5AC5-5766 /boot/efi vfat x-systemd.automount,noauto,umask=0077,shortname=winnt 0 0 UUID=8fd67b94-0dd5-4df0-a690-066460e47fd8 / btrfs subvol=root 0 0 UUID=8fd67b94-0dd5-4df0-a690-066460e47fd8 /usr btrfs subvol=usr 0 0 UUID=8fd67b94-0dd5-4df0-a690-066460e47fd8 /boot btrfs subvol=boot 0 0 UUID=8fd67b94-0dd5-4df0-a690-066460e47fd8 /home btrfs subvol=home 0 0 Boot and updates with yum, dnf and pk-offline all work. The stateful settings and files in /var, /etc, and optionally /home can all go together on root. And stateless stuff on /usr. This seems more coherent than a bunch of different mountpoints under var; and even var on its own has been rather problematic. I'm guessing the installer doesn't permit separate /usr for legacy, pre-usrmove reasons. This layout is also compatible with the proposal found here: http://0pointer.net/blog/revisiting-how-we-put-together-linux-systems.html -- Chris Murphy -- test mailing list test@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe: https://admin.fedoraproject.org/mailman/listinfo/test
