Thanks!
I am unfamiliar with what the proper workflow might be for this, but I opened a PR in case that's the right path. I poked around in https://devmanual.gentoo.org/keywording/index.html and I didn't find content regarding how to add new keywords to packages. Let me know if I've missed it and if I did it incorrectly ☺
In particular it wasn't clear to me if I should send a PR, or if I simply needed to ACK on this bug. In case the latter, I'm happy to close the PR, and: ACK ☺
I learned from Sam in the PR that since I don't have an ARM Gentoo system to test with that I should not send a PR, so I am removing the PR from this issue. I don't have firsthand knowledge of whether lnav officially supports ARM for Linux, but I don't know of any reason they wouldn't, and I do see that they officially support ARM for MacOS: https://formulae.brew.sh/formula/lnav It sounds like I should leave this ticket for the arch teams to do, but let me know if any further action is requested from me.
