I imagine Signal is probably fine unless you’re doing some real weird shit.

For like 99.9% people, it definitely is.

To counter this, my experience was completely different. The transition was very easy.

Just set up some type of snapshots (I used Timeshift with auto snapshots made before every update and made available immediately on grub boot menu).

I ran EndeavourOS for over a year this way, and broke it a whole bunch of times while learning the ins and outs. Timeshift was clutch, and made reverting any mistakes super easy.

Now I’m on Bazzite, which is atomic and immutable, so I don’t really worry about breaking anything because I couldn’t if I wanted to (I mean I could, but it’s not easy).
