Installing Devuan Ascii 2.1 with virt-install

The branding of the ISO file was updated sometime after the devuan_ascii_2.0.0-beta_amd64_DVD.iso, so that it shows "Devuan GNU/Linux" as shown below.

$ isoinfo -J -i devuan_ascii_2.0.0-beta_amd64_DVD.iso -x /.disk/info
Debian GNU/Linux 2.0.0-beta "Ascii" - Official amd64 DVD Binary-1 20180213-18:54
$ isoinfo -J -i devuan_ascii_2.1_amd64_dvd-1.iso -x /.disk/info
Devuan GNU/Linux 2.1 (ascii) amd64 DVD1 - 2019-12-21 07:24:54 UTC

When this branding changed, virt-install could no longer identify this iso file as a Debian (or derivative) distro, so it could not pull from a built-in list of initrd and kernel files to load.

On my virtualization server (CentOS 7, virt-install-1.5.0-7.el7.noarch), I patched /usr/share/virt-manager/virtinst/urlfetcher.py to handle a Devuan disc.

It looks like upstream virt-manager has moved in from virt-manager 1.5 and has refactored the code, but file https://github.com/virt-manager/virt-ma … ldetect.py is the one that could be patched to include Devuan disc info.

Do you expect that the initrd and kernel file names on the install media will be stable? I would not mind submitting a patch to upstream. I have no relationship with them, but I want Devuan to be easier to install on virtualization platforms!

Re: Installing Devuan Ascii 2.1 with virt-install

Which package contains isoinfo? And is there a way to search for packages containing a particular file?

Thanks, got it installed now, and apt-file installed as well.
