I'm wondering if these packages were prepared on a system that had /usr/bin/mkdir even though the standard debian image is /bin/mkdir.

This depends on the version of Debian. On Debian 12 bookworm the standard path will be /usr/bin/mkdir, and you can get that on Debian 11 bullseye today by installing the usrmerge package, which gets installed by default on new standard installs. For more info see the Debian UsrMerge wiki page. For really deep why, see Booting Without /usr is Broken.

The Debian Docker image doesn't have /usr/bin/mkdir out of the box, but maybe we could add a dependency on usrmerge as a workaround?

I think that's worth a shot at least.

Digging into the GitHub issues a little more, it sounds like RVM builds on Ubuntu, and Ubuntu recently did a dot release that merged /usr, probably because Debian bookworm is close enough that it made sense for them. But then builds fail on systems that don't have merged /usr.
