How about the reuse of btrfs subvolumes?
It is possible to reuse btrfs subvolumes for mount points other than root. Root requires a
new subvolume.
It seems to me that the only way to do that is to delete the
subvolume and then reallocate it which is precisely what I do in my KVM kickstart
installs. I first bootup in rescue mode and delete the old root subvolume and then reboot
to do the install. I probably need to figure out out a pre-install script which will do
that.
No need to delete the previous subvolume unless you want to delete the installation
contained on it.
Is this worth an RFE? I am thinking of an RFE for kickstart. I assume (I have not
tried it) that I can reuse an subvolume by first deleting and "reclaiming" the
space from a regular install.
Reuse is inconsistent with delete, but yes you can't reuse an existing subvolume for
rootfs for a new install.
