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 directory, 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? Tomas -- There are only two hard things in Computer Science: cache invalidation, naming things and off-by-one errors.
