Okay, here is a difficult one (glibc broken, no reboot)

If you could help me fix THAT problem, you're the hero of the day!

Introduction: My gentoo server has been running for many years. I recently started an emerge -vuD world. Glibc was one of the libs being updated.

Problem is: Now with Glibc updated from 2.9.x to 2.10.1, most parts of the system have stopped working. For example grep, make, udev...

I get errors messages like that:

grep: relocation error ... GLIBC_2.3.2 not defined ...

Which also prevents emerging almost anything. Now, as udev has stopped working, my /dev directory is completely empty. There is now way to mount a CD or a usb stick to unpack a stage3-tarball. Networking (ssh) is also corrupt.

To conclude: With Glibc replaced, the system is in an inoperable state. There seems to be no way to get anything into the system as udev isn't working.

AND: I have no intention of rebooting since I setup a dm-crypt over software-raid a few years ago and I fear of not being able to restore that setup and losing valuable data...

So, what would YOU do?

After rereading your entire post. I doubt that this will work.

Okay. I got my /dev/cdrom file back, by unmounting /dev/. (Yes, unmounting)

Now my plan is to untar a fresh stage-3-tarball in /.

But, is that possible from the running system?
