The config file is bash and it gets sourced, so all bash magic is
doable in there as well. Document it so others don't have to
re-discover this gem as well.

But I'm curious about this specific example. Is this not mounted for you
automatically? I'm guessing systemd does it for me on my setup.

No my setup is kind of special. I don't want to mess with all the
user-space so all I do is:
dracut --no-compress --kver `make kernelrelease` --kmoddir mods/ \
--no-hostonly --no-hostonly-cmdline --modules "bash base" \
--tmpdir `pwd`/myinitrd --force myinitrd/initrd \
--add-drivers "loop nvme nvme-loop nvmet" \
--install "lsblk find sort parted getopt fio tput column date \
dirname mktemp ps diff awk timeout time losetup \
truncate wc grep stat basename cut blktrace sg_inq \
realpath findmnt vi dd sed rm rmdir nvme" \
--include "$HOME/src/blktests" "/blktests
qemu-kvm -m 4096 -smp 4 -nographic -serial mon:stdio -kernel \
arch/x86/boot/bzImage -initrd myinitrd/initrd \
-append "console=ttyS0 debug"
I have the above in a shell wrapper as I simply can't remember it, or
I just use rapido [1] which a co-worker of mine started for this job.
As minimal as possible. I try to get my rebuild - boot - test cycles
short.
With my current config I have a bootup time in qemu below half a
second on a reasonable machine in my lab and just below one second
on my laptop.

Cool setup :) I have my own fanciness [1] which lets met boot straight
into a test kernel without packaging it up in any way.
Anyways, I added some documentation based on yours. Thanks!
