I then copied over my /etc, world, all the portage stuff such as distfiles, binaries and the tree as well. I also copied over any local overlays I had as well. Since I want to end up with a system as close to what I have, so that the binaries will be a perfect match, I figured copy over all the variables and settings with it. I can't even get through a simple emerge -e system. It's either circular deps, slot conflicts or some other error. The last one was something about a corrupted /dev. I'm not sure what to make of that yet. After I got that, it refused to do anything at all. It acted like it was out of drive space/memory or something but it isn't. It's on a 750GB drive with a lot of space left yet. I have 32GBs of memory here with 3/4s currently available. So, I'm doing a rm on that and starting over from scratch. I guess I'll just have to move the contents of world over a few at a time and hope copying make.conf and the USE line over won't break anything. I'm sure it was my method. I likely overwhelmed emerge but I'd hate to know I had to reinstall from scratch and get back to a identical install. Some things that I vaguely recall; freetype, harfbuzz, zlib and issues they created. I got around a couple others easy enough but it basically suicided itself after that. Off to try this again. Dale :-) :-) P. S. Starting to wonder if I should copy my current install over and start there. I'd assume skipping /home, /proc and /sys would get me started. Still, gonna try the stage3 again. Just for giggles. Do all this while I cook some BBQ chicken for supper tomorrow night.

James I am very interested, although my testing capabilities would be restricted to a non-samsung Pixel 3. My understanding is also that the Pixel and Nexus devices publish their "vendor blobs" or hardware binaries online which may help? I've experimented with Ubuntu Touch a bit on the Nexus 5, however the device is quite slow at this point. My use case wouldn't be so much for control over updates, but more for things like Convergence (Ubuntu), Dex (Samsung) or Android Desktop. Where you dock your phone and have a linux/Android desktop with floating windows etc. I'd like to be kept in the loop on this, and if possible I would also like to help contribute software however I'm not really skilled with hardware. I configure my kernel and that's about it.

Is that not the behaviour you are seeking? OR is that not the behaviour you get? I'm not sure if you got my point. Most of the time, I don't need that option. When I do need it, I discover that fact because the system won't boot into a usable state. I can boot into a live CD, edit rc.conf, then reboot again. My desire is to be able to get that interactive boot by doing something at boot time, so I don't have to reboot twice. However, on reading that explanation again, and more slowly, and more carefully, and actually absorbing it, I finally see that setting rc_interactive="YES" won't really have any effect on normal boot, but only if I press i or I at boot time - so I will have to try that. Thanks for poking me in the right direction. Also to note: rc_parallel="yes" may cause the boot process to lock up. (I wonder if that has been causing some of these boot freezes.) I hadn't considered that, and it might well be relevant, but in all my own cases, I was able to find a single service which was causing the problem. rc_interactive="yes" is DISABLED (automatically), if rc_parallel is set to "yes". -- Best of luck Roger Thanks, Jack

I have a skeleton filesystem tree in /var/lib/machines/multimedia-state that bind-mount read-writable stuff. Everything else is read-only bind-mounted from my root FS.

[gentoo-user] Gentoo on a cell?
So, After contacting several US carriers, the cover story is you can get a cell phone, root it with linux, and it 'should work'. Supposedly, you are encourage, but they will not offer any help. So rather than spending months, I'd like to 'cheat' and find a gentoo hack(er) that has rooted and put some form of gentoo, or embedded_gentoo on a cell phone.

I was able to boot adding init=/bin/bash to the kernel command line, but then even though I could do "openrc sysinit" then "openrc boot" and then start "default" services individually, it took longer, since I had to try to figure out in what order services would have been started. I wonder if booting with init=/bin/bash, editing rc.conf, and then doing "exec /sbin/init" would then put the system in a state (with proc 1 being init) as if it had booted normally, but with an interactive startup?
