add flag to refresh the flake #1112
Description
I'm currently tinkering with a disko setup, via a flake in a git repo. I'm logged in on the target machine via ssh and trigger sudo disko-install -f git+https://... with a git based flake url, while ammending the last commit on a dev branch of that git repo using another computer.
However, flake caching hits me, disko does not each time re-fetch the flake. To manually trigger a refetch, I run sudo nix flake show --extra-experimental-features 'nix-command flakes' --refresh git+https://... in between. The sudo in the second command is needed, as individual users have individual flake eval caches AFAICT. It would be really nice to have flag for disko-install (and disko?) to directly opt-out of flake caching; in these cases the cache is more of an anti-feature IMHO.
