Ceph

Hello!

Attempting to use ceph-volume when LVM is installed in a non-standard location results in:

$ ceph-volume lvm list
--> Absolute path not found for executable: lvs
--> Ensure $PATH environment variable contains common executable locations
--> Absolute path not found for executable: lvs
--> Ensure $PATH environment variable contains common executable locations
No valid Ceph devices found

Yet:

$ which lvs
/root/.guix-profile/sbin/lvs

The problem is that, despite the error message, ceph-volume never actually consults $PATH. It only searches a hard-coded list of locations.
