The explanation of
sysroot.readonly
is a little confusing - we say that "everything else is mounted read-only" but it's perhaps clearer to say/sysroot
is mounted read-only.Also note that read-only is the default with composefs.
Finally, document the option in ostree.repo-config even though it is now considered legacy - as of commit 22b8e4f (#2930) - it is still commonly seen in repo configs, so users will look to understand what it means.
