Thanks! Fortunately, it's not as bad as it looks--it's mostly a matter of
reading the udev rules files and writing a script that does the same thing
:)

Yeah, it can get pretty tedious. Fortunately, I'm using a minimal QEMU
image, so reboots happen pretty fast (i.e. the working set fits entirely in
my disk cache).

I have developed a new-found appreciation for the people who designed
Debian's initramfs system. Despite the tediousness of building cpio
images, Debian's initramfs-tools package is surprisingly flexible and
well-documented. There are a couple little things it could make the
process less painful, though; I'm in the process of getting together some
patches to send to Debian, if they're interested.

Absolutely! I intend to make the first iteration of packages available as
direct downloads (will post hashes to the ML), and will continue to do so
until I can figure out how to hook the vdev repository into Devuan's CI
system.

Thanks,
