> * Add support for ISO images.
For ISO images, by running make-iso9660-image directly on the host (see
wip-disk-image branch), I have a considerable time decrease.
This command:
--8<---------------cut here---------------start------------->8---
guix system disk-image --file-system-type=iso9660
gnu/system/examples/bare-bones.tmpl
--8<---------------cut here---------------end--------------->8---
takes,
* Without zisofs compression, on host: 4min
* With zisofs compression, on host: 8min
* With zisofs, on VM: 19min (master)
This makes me think that we may want to make iso compression optional,
so that tests can use uncompressed iso that takes more space but are
faster to produce.
It seems that there are also some alternatives to xorriso such as
genisoimage (used by genimage).
