I am trying to build a bash script that automatically downloads the latest stable nixos iso.
I am trying to build a qubesOS builder for NixOS (see Redirecting…)
I am working on the 00_prepare.sh script.
I am hoping I can do something like:
BOOTSTRAP_TARBALL=$(wget -qO- "$ARCHLINUX_SRC_PREFIX"/iso/latest/sha1sums.txt | grep -o "archlinux-bootstrap-[0-9.]*-x86_64.tar.gz")
Except obviously it would be a iso format. If it could be a tarball that would be great too.
Thanks in advance!
If you’re okay with unstable, you can use this URL:
Unfortunately we don’t really have a “nixos-stable”. It has been requested before, but I can’t find the ticket right now. If you know which NixOS version you want, you can do something like this:
URLs like nixos-19.03 release nixos-19.03.173691.34c7eb7545d might be useful to you, though probably not as easily as you’d hope. EDIT: the final slash was breaking the link 
Hey, I have been considering trying to tackle this exact same project lately as well… Are you sharing your attempt publically at all?
Thanks! I’ll try making this work.
No clue what you’re trying to achieve but this https://github.com/cleverca22/nixos-configs/blob/36c6dfb5ce0e48ea7f24ad6602cb1203fa44e41c/multi-boot-helper.nix lets you generate an installation image and the upside is you choose which version of nixos you want by modifying the top import.
