If you want to go play with /etc/fstab and you have a concept of "everyday cli tools"an immutable distro is not for you.
Please don't conflate stuff.
On Fedora Atomic^[And probably most distros that are -perhaps erroneously- referred to as "immutable", though the finer details might be different.], it's possible to:
- Change the content of
/etc/fstab. Heck, the same applies to everything under/etc. The only difference being that a pristine copy is kept at/usr/etcAND the fact that any changes to/etcare being tracked. Said changes can be accessed withostree admin config-diff. - Install CLI apps just fine. Refer to this comment for more details.
An immutable distro is made for people that do not use a computer but use a browser.
False. Again.
While I agree that it's a very sane recommendation to the technologically inept, it would be a huge disservice to suggest it can't handle more advanced workloads. Because, quite frankly, there's very little it actually fails at. And most of its user base would vouch for this. And that list of restrictions/limitations is becoming smaller as we speak...
