I once talked to someone on iirc Linux discord server about their project which was very similar to this (An Immutable arch/(maybe cachy?)) which they had built.

There is quite some innovation within this space of (atomic-arch?) which I am interested about because I wish to recommend arch's bleeding-edge/aur to people and the ability to have snapshots etc. is interesting, which is something that I might need myself as well... as I really get too lazy at times for snapshots.

With their talks, I used to think that it would become very bloated distribution/might not work fast but that's not really the case.

In future, I will take a look at arkane as well!
