Embedded recovery system (was: Bare X, please)

I would like to know how can I disable the X => OpenGL dependency. I want to install a barebones X into a pendrive Gentoo setup (embedded, uclibc, that kind of things). I try to emerge xorg-x11 and a _lot_ of dependancies get pulled in. Among them are virtual/opengl, virtual/glu, virtual/glut, media-libs/mesa, libXcomposite, libXinerama and many things that my embedded setup will obviously not need. I have enabled the "minimal" USE flag and disabled the "dri" one, but the situation is still the same. Here is the package list portage spits out:

Copy the xorg-x11 ebuild into your portage overlay and modify it to your heart's content.

That is what I ended up doing with the gnome ebuild. gnome-light didn't provide enough and I really just wanted to strip a few things out of the default gnome.

Hmm.. I have discovered that emerging just xorg-server provides a lighter setup, but it still wants to pull mesa. I suppose I'll end up using your overlay approach. In fact, I'm doing just that with baselayout-2, which wants to pull coreutils (but I want busybox). I've thought of creating a new virtual/coreutils and then making both busybox and sys-apps/coreutils provide it. Would that be too difficult or is it The Right Way (TM)?

I thought that X depends on Mesa at compile time...

Why would that be so? Isn't the point of modular X building just what you need and not a single additional line of code? libdrm and mesa are two _big_ libraries, especially the last one (6MB), which I don't have any use for. If my X server receives OpenGL/DRM requests, it should just answer "not supported, sorry".

Well, I've got X now (dunno if it works, I haven't tested anything yet), but the next problem appears: e2fsprogs fails with the following error:

Update: I found there was a configure option called --disable-tls, so I copied the ebuild to my overlay and edited it, created a new "tls" USE flag and kept it disabled. Then e2fsprogs built completely fine. Is there a way to have that change merged back into the official Portage tree? Do I need to file a "bug" to request such an USE flag be created in that package?

I've just ran into the exact same issue (with a uclibc setup), so I'd go ahead and file the bug report if I were you.

Thanks for saving me from having to find a solution myself (gods, I love the forums at times like these).

You may want to try xdirectfb, I am currently compiling it so Ill let you know my results!

Off topic, but heh, shoot me:
I am also trying to build a uclibc based system but am having some problems with the latest versions of packages not being supported, how are you guys progressing and avoiding these problems? I am currently rebuidling using an old version of the portage tree (2006.1 snapshot). I found that here are a load of pre-build packages which look recent, so I might give that a go too.

I would say 'no'. I installed xdrivefb but it complained that xauth, xinit and mcookie couldn't be found.

I am trying to create a system with just internet access, with nothing fancy, although I would like Javascript support so that'll mean Firefox or Konqueror. Konqueror seems to be lighter than Firefox (for memory and CPU), but it requires all the KDE deps. :roll:

Update:
Well I got kdrive installed and it seems to work well, I now have a running X system in 6.8mb!

Unfortunately I can't compile anything else as no X headers or libraries etc were installed. I think I am going to have to install full X, build everything, then uninstall it and run everything through kdrive.... Hmm.

Indeed... it's a known issue (https://bugs.gentoo.org/show_bug.cgi?format=multiple&id=204102). I downgraded to e2fsprogs-1.40.3, which is good enough for me, and it seems to be working fine. Thank.
