Hi Jesse,

Do you observe the same problem with the image I linked to above?  It’s
built with ‘guix system disk-image -t iso9660 --label=GUIX…
gnu/system/install.scm’.

The error you sent looks as if it’s trying to mount the root file system
read/write.

Thinking about it: does it work if you pass ‘--volatile’ on the
‘disk-image’ command line?  This flag was added recently on ‘master’
(commit 41f27bf8702838f19b1dc5ffee8eec1d4315d4e6), so perhaps what
you’re seeing is a regression here.

Maxim, could it be that we need (volatile-root? #t) for the ISO9660
image type and/or passing ‘--volatile’ in Makefile.am (‘release’ target)
and updating the “Building the Installation Image” node of the manual?

Thanks,
Ludo’.
