Looking to create custom Artix based VM boot images with a mechanism like buildiso where packages can be hand picked. QEMU being used to test these for now but cloud-hypervisor is the ultimate target (so no virtsh/libvirt). The ISO images from buildiso have multiple rootfs overlays that are quite the pain to figure out, I'd very much like to mount a single disk image (with or without partitions) with a straight up writable ext4 or squashfs for root.
The boot log from my present state of progress ends with:
...

@done.

ERROR: Failed to mount the real root device.
using a kernel command line of:
edd=off locale=en_US keymap=us trace_clock=local amd_pstate=disable loglevel=9 console=ttyS0,115200n8 earlyprintk=serial root=UUID=f8f4300c-1a80-4ca7-8e5f-1acd6c1dd243 label=ROOT_PT
I can set label=BOOT_PT as clearly /run/artix/bootmnt is the wrong place for a rootfs, but there is nothing useful in the BOOT_PT partition and then the rootfs mount fails the same way as above.
Anyway, the artix packages artools and iso-profiles got me this far, but I've been hoping a vm-profiles or cloud-profiles would be lurking somewhere?
Fastest path now would be to tweak the running hook scripts, which are found in (one of ?) the /hooks root directories, but I've not been able to find the artix package that buildiso is using to provide these.
As this is a clearly a feature ask, I'm not expecting support, but I'd appreciate it if anyone has a pointer or idea ...
