Does that make sense though? You have already made an exception for
/tmp, I would argue that ~ is another candidate for special-casing.
I think people would reasonably expect that touching a file in your own
home should work. But it does not:
--8<---------------cut here---------------start------------->8---
$ guix shell --no-cwd -C coreutils bash -- sh -c 'touch ~/foo'
touch: cannot touch '/home/user/foo': Read-only file system
--8<---------------cut here---------------end--------------->8---
Some software just fails to start in the container:
--8<---------------cut here---------------start------------->8---
$ guix shell --no-cwd -C deluge -- deluged
20:22:20 [ERROR ][deluge.common:136 ] Unable to use default config direct=
ory, exiting... ([Errno 30] Read-only file system: '/home/user/.config')
--8<---------------cut here---------------end--------------->8---
Sure, I *can* use --writable-root, but I agree that root being read-only
is a good idea. Maybe --writable-home, which would default to #t, would
be a good addition?
