Tbh, Linux atm needs a good way to restore incase something goes wrong. The rule to use a USB stick and then chroot and fix is not the best idea.
A week ago I ran into issue where my Storage ran full (I was downloading+ manjaro was updating in BG) and then apparently the system didn't boot up coz of this. It took me sometime to realise this issue and fix it.
You can't expect an avg user to be able to perform so much.
Another incident, My friend somehow ended up in a state with no kernel installed and thus couldn't boot up.
Well Im trying out sync and it's honestly such a good and polished app. A big Kudos to the dev. Would probably buy the premium if the pricing goes down.
