Hi. Why isn't in Portage "new" lilo-22.7.1? :)
And eventually http://home.san.rr.com/johninsd/pub/linux/lilo/beta/lilo-22.7.2-beta6.src.tar.gz too. We can help them with testing. :)
Has been bumped to 22.7.1; with regard to the other version, a bootloader is not something I want to experiment with. This seems beyond ~x86 & ~amd64. Feel free to add it in your own overlay. Thank you for your report.
