Concerning linux, yesterday I was watching this video on computerphile on the crowdstrike incident. https://www.youtube.com/watch?v=rlaNMJeA1EA (*)
What is interesting is the comment made in the video on how chromebooks do software upgrades with dual "OS" disk-partitions and the ability to rollback to the previous OS-partition.
Question: is something like this also possible on one of the major linux distros? (debian, ubuntu, rocky, ...) What would be the procedure to do this kind of "dual partition" system-upgrade?
(*) a great video that explained some of the technical details in a very clear way, including some very interesting 'lessons learned' and "what if"s If you ever need to explain crowdstrike to your manager, this video is a good start.
@kristoff @purplemonkeymad Try openSUSE (RPM family), Garuda Linux (Arch family), or Spiral Linux (Debian stable) or siduction (Debian testing). All have snapper and on Btrfs do snapshots and rollback.

@kristoff @purplemonkeymad But watch out: you will need a *huge* root partition, because it's very easy to fill it with snapshots and if it reaches 100% it *will* corrupt.
Btrfs is tricksy: it won't give a straight answer to
df -hand there is no working equivalent offsck.@kristoff @purplemonkeymad All of these are in-place same-disk snapshots. The ChomeOS system is simpler and so can be automated but you only get 1 level of undo.
I don't know any mainstream OS that does dual-failover. Deepin Linux has 2 root partitions but I don't know how it uses them.
I think Valve SteamOS does something like this. It's not just for games: it has KDE built in. There are guides to getting it running on your own hardware. You will want AMD graphics, though.
As I mentioned earlier, I guess chrome is more like android where you have a much more strict seperation between the OS, applications and user data. (I remember reading about all the different partitions on android and what they are used for, but I should bruch up my knowledge on this).
Thanks for the additional into on brtfs! 👍
@kristoff Not really... On ChromeOS, there are no apps.
No apps at all ???
So it really is like a dumb terminal. Now I know why I never used a Chromebook😀
