I have f21 installed into btrfs:
sudo btrfs subvolume list /
ID 256 gen 1818195 top level 5 path home
ID 259 gen 1818195 top level 5 path root
Now I want to install f22 into a subvolume. I assume that I need to create
the subvolume 1st (while running f21), and then I can get anaconda to
install into it. But I don't know how:
[nbecker@nbecker7 scma-unframed]$ sudo btrfs subvolume create /f22
Create subvolume '//f22'
[nbecker@nbecker7 scma-unframed]$ sudo btrfs subvolume list /
ID 256 gen 1818179 top level 5 path home
ID 259 gen 1818179 top level 5 path root
ID 488 gen 1818179 top level 259 path f22
This created f22 which looks different than the other subvols - I think I
want an f22 which is parallel to 'root', not a subvol under root - but I
can't guess the correct syntax for that.
So the idea is that 'root' would be my old f21 system and 'f22' would be
my
f22 system. I hope I understand this correctly.
