[qubes-users] Dual booting Qubes and Qubes?

2019-12-15 Thread Claudia
I'm wondering what the best way is to go about installing two instances of Qubes 4.1 on the same machine, which are more or less independent of each other. It's fairly easy to dual boot different OSes because they each have their own EFI directory, e.g. /boot/efi/EFI/{qubes,fedora,ubuntu},

As to the first question: with qubes 4.0 it is a bit difficult to effectively wipe free space in the default thin pool. One can create a thin volume and write to it until the thin pool reaches some saturation level (99.5%), then hit that volume with blkdiscard before invoking lvremove. Because
