thanks for the quick reply and apologies for my late one. for some reason i never received an email notification about your reply.
i am a musician who got started on Gentoo for various reasons, so i am no Portage expert ;) however, i appreciate the flexibility and freedom offered by Gentoo+Portage and can handle day to day things. as i mentioned i am just trying to make maintenance and compiling less of a time commitment. i was thinking that binary packages would help in that regard greatly. in fact, i had tested Sabayon which seemed like a perfect fit. unfortunately it seems geared towards newer hardware, and i am not convinced by systemd, so still looking for something Xtoo-based but using binary packages.
actually i am a bit surprised that there are not more Xtoo/Portage based distros using binary packages. it seems like a perfect next step for a Xtoo-based derivative that is trying to be less difficult to maintain, possibly more environmentally* friendly with less compiling. so far Sabayon seems to be the only one.
if i understand your proposal correctly, in trying to create a new stage 4 and LiveCD for Funtoo you would also be setting up a binhost server? i am not sure how a binhost server works, but i assume that all/some packages are compiled with different -march settings as they are released. thus my machine would try to pull matching (arch and USE flags) binary packages on emerge, then compile what was not available. am i getting this at all? ;)
my current arch is not new:
Linux Barbone 4.4.2-rt-gnu-rt7 #1 SMP PREEMPT RT x86_64 Intel® Core2 Duo CPU P8700 @ 2.53GHz GenuineIntel GNU/Linux
so not sure if that could also be supported by your binhost? if so, and if i can get going my normal music software going with a new Funtoo install, i could use it, give feedback, etc. unfortunately that is all i can help with right now.
please let me know if i am following you and if your binhost server could support that arch, and we can go from there.
* as environmentally friendly as computers can be ;)
