Interesting experiment..

I repacked fsr's iso (otherwise unmodified) using the initrd from the
devuan-minimal-beta. That initrd was also repacked and xz-compressed
(now 8.5MB).

I booted it "findiso" (from iso file on an ext4 partition) with a
"live-hook" script, which automatically loads my specific wlan
firmware and autoconnect configs.

It booted a fully functional XFCE4 in seconds. Everything seems to
work, posting from it right now.

Sometimes I use a FAT-formatted USB similarly, sometimes with a LUKS
persistence file. Obviously, initramfs must be able to access
filesystems other than iso9660 to do that.
