chattr: setting flags on /etc/shadow: Operation not permitted

On multiple of the examples, I see the following error:

$ docker run -it nixng-apache
Running fragment cacerts
Running fragment createBaseEnv
Running fragment currentSystem
Running fragment iana
Running fragment runit
Running fragment shellProfile
Running fragment tzdata
Running fragment users
chattr: setting flags on /etc/shadow: Operation not permitted
<--- Stage 2.2 --->

It does look like the containers works correctly though!

Yeah it appears to be a thing with rootless containers, the /etc/shadow file is somehow more protected. Haven't looked into it as the containers work as expected, as you have noticed :)

Can confirm this seems to be an issue with rootless docker. But I don't think it has to do with /etc/shadow being more protected, I cannot do chattr +i on any file.

Oh okay, so we just need to detect rootless? Well we could also silence the error but detecting rootless is better.
