You probably just need the linker/loader from that tree - or are there also some libraries there, that work with it?

Why not using the atime mount feature for your purpose?

Which file(s) should I try keeping there?

I'm not sure what you mean. I think atime is default. Do you mean noatime to reduce IO?

relatime is default mount option.

If you are using the old full atime option for some time
and you do all the things you want to do later on the other machine
but in that time frame nothing not wanted on the other machine

then you should be able to atime sort -r files and get a clue what is needed for your minimal system.

Don't worry about /run: it's a tmpfs created at startup. The most you should do is: mkdir "$ROOT/run" (and I'm not sure that's even required.)
/var/spool is where user emails typically get buffered during reception, as well as eg print jobs, so yes you should consider it private. /var/lib/portage/world is usually the most important thing under /var ime, but you said there's no portage on there, so not required.

Apart from that, what jrg said.

If I were to dump all of this extra stuff it would almost get down to 4GB. In the past I've used a different approach to get a super-minimal Gentoo system under 256MB which I load to a ramdisk on the 256MB Beaglebone. I felt pretty cool about that.


I would think it would be less than 4. On a fresh install with nothing other than the core system, xorg/openbox, and video drivers I was still well under 5GB

It's not a fresh install though. I should have mentioned that. It has all of my stuff.

That doesn't matter if you have not done badly /etc config. But if I'd known you didn't update your system regularely I'd told you better in the first place. Generaly is better on a rolling release to roll. And I don't know what you fear doing it using the stable Gentoo distribution ...

If you have done some bad decisions as admin of your system (etc config) you might get problems. Otherwise there is no problem rolling a stable Gentoo distribution regularily. But there will be problems if you wait too long. Once a month you should do. And it is less a burden to update once a week.
