Hi Jaco, Sounds reasonable.
It's unmaintained, has c99 issues, and it looks like you were actually the last activity upstream, logging a ticket... in 2016, so I'm more than comfortable with your suggestion. When you're ready to submit the PR for xl2tpd you can send out the last-rites email to -dev and -dev-announce and include an additional commit for corresponding p.mask. There's a good page in the dev manual that goes over the whole process: https://devmanual.gentoo.org/ebuild-maintenance/removal/index.html Feel free to ping me on the PR and I'll take a look. Cheers, Matt
