[plug] updating glibc on old RH6

[Joel Johnson]

Hi folks, have a client who has an old Red Hat 6 machine. I need to 
install some software on it that requires at least glibc_2.2.4. 
Unfortunately it seems RH6 update rpms only went as far as 
glibc_2.1.something.

Is anyone able to tell me whether I can install, say, a RH7 update RPM 
for glibc_2.2.4 without killing anything else?

Client is dragging their heels over upgrading to newer distribution - 
the old "if it aint broke" mentality as well as the cost excuse - so at 
present that's not an option.

Thanks in advance.

Joel
