It depends somewhat on what version(s) of libc are involved, and what
distribution you're running.  In general though, upgrading glibc on a
running system is often met with disastrous results.  If you really
need to do this, you're probably best off saving off your data
somewhere, and re-installing (a more recent release of your favorite
distro) from a fresh fdisk...

However, if you're really brave, on a RH system, you can rpm -Uvh the
glibc RPMs.  If you're upgrading to a different major revision
(e.g. libc 5 to libc 6), you'll likely find that lots of stuff won't
work.  For that matter, you may find that going between minor
revisions (e.g. glibc 2.1 to glibc 2.2) you have the same problem;
I've never tried it, so I can't really say.

In theory, on a debian system, you should be able to do a 

  apt-get upgrade glibc

or some such thing, and it should go and get everything you need to do
the upgrade.  Personally, I have my doubts.

If you really, really, really want to upgrade libc, your best course
of action might be to download the source from GNU and read all the
docs, especially anything you can find about upgrading on a running
system.  From what I understand, this is not a task for the feint of

Good luck!
