I have trouble building the documentation in sage-on-gentoo because of #30352
which doesn’t seem to be
implementing features properly. That error wouldn’t happen on vanilla sage
because the build is not done
in a sandbox and the build system wouldn’t try to write a system location.

Various bits of sage try to recreate share/knotinfo/num_knots.sobj which isn’t
installed because I haven’t
packaged it yet. This shouldn’t be an issue since database_knotinfo is still
optional.
The problem here is that it seems that _feature.is_present() is always true,
including when it is called
at
https://github.com/sagemath/sage/blob/develop/src/sage/databases/knotinfo_db.py#L416
I cannot find where it could be found as being false in the current code.
