Thanks! Longer term I intend to create a Guix-centric web frontend for Ganeti similar to <https://grnet.github.io/ganetimgr/>.

For integration with common "cloud" providers (Openstack, AWS, etc), it would be great to create a VM (or disk) image that does this on boot: 1) Resize partition to use whole disk. 2) Reconfigure/init from a configuration file URL, typically a provider-specific method of providing metadata to VM. 3) Possibly runs `guix pull` against some similar metadata parameters. Then Guix could conceivably be supported by other provisioning tools that works with such systems (Terraform etc). This would also go a long way towards PXE booting... I haven't really given "GuixOps" a lot of thought until now, but I imagine a more low-level administration tool along the lines of... $ guix machine --add htpc htpc.local $ guix machine htpc reconfigure ~/dotfiles/guixsd/xbmc.scm $ guix machine htpc reboot "reconfigure" here would build the system locally and send over the closure, so that the remote system never needs to `guix pull`. For provisioning, maybe something like... $ guix provision --provider pxe ceph-osd{1..21} <spec> $ guix provision --provider ganeti guixbuilder{1..4} <spec> <spec> would adjust hostname and IP addresses according to some criteria and register the machines. This is loosely inspired by xCAT <https://xcat.org/> and would require a stateful database. Now I'm getting carried away: $ guix machine --edit r2d2 --ipmi [email protected]:password $ guix machine r2d2 console (SOL) $ guix machine r2d2 powercycle (IPMI/API) Arguably some of this falls well outside the scope of Guix, but I do think there is room for an all-round systems management solution.
