it's more likely for readers to find it right there.
this also slightly rewords examples to make them stand out better.
in the long run there probably needs to be a dedicated section on formal syntax, and better highlighting of examples.
This requires switching on SQLITE_OPEN_URI because there is no open flag to
make the database immutable. Without immutable, sqlite will still attempt to
create journal and wal files, even when the database is opened read-only.
https://www.sqlite.org/c3ref/open.html
The immutable parameter is a boolean query parameter that indicates that the
database file is stored on read-only media. When immutable is set, SQLite
assumes that the database file cannot be changed, even by a process with higher
privilege, and so the database is opened read-only and all locking and change
detection is disabled.
e.g. nix-env -e subversion => nix-env --uninstall subversion
The aim is to make the documentation less cryptic for newcomers and the
long options are more self-documenting.
The change was made with the following script:
<https://github.com/aschmolck/convert-short-nix-opts-to-long-ones>
and sanity checked visually.
- If the element comes from a flake, print the full flakeref (with the
fragment part) and not just the reference to the flake itself
- If the element doesn't come from a flake, print its store path(s)
This is a bit too verbose, but has the advantages of being correct (and
not crashing), so it's strictly better than the previous situation

This gives some more context and should clarify why it works that way.
Also link it from the section on `NIX_USER_CONF_FILES`.

Nix does not manage the overlayfs mount point itself, but the correct
functioning of the overlay store does depend on this mount point being set up
correctly. Rather than just assume this is the case, check that the lowerdir
and upperdir options are what we expect them to be. This check is on by
default, but can be disabled if needed.
They were improperly added in 8a93b5a551.
They were not `.gitignore`d because they were stale in that commit --
build artifacts no longer used that name by then and so `.gitignore` was
updated accordingly.
