[HanoiLUG] Chrooting into an environment for a higher glibc, libstdc++, libgcc...

[Steve]

I have a requiremnt to run a new version of a java app on RedHat 7.2.

And one of the ldd dependancies of this app is for libstdc++.so.5 (and
therefore libgcc and glibc...).

Now I could install just the 3 libraries locally and do some
LD_LIBRARY_PATH trickery, or I could install a basic modern os such as
ubuntu (or RH/fedora/centos spawn if I
really have to), amd of course the java jre and this app, and then
chroot into
the new environment (would have to also bind the existing /tmp and /home
into the chroot for X, hey?)

Would this work?
What about the chroot environment running with a new x.org, say (and not
xfree86)? Would I have any udev issues since the running kernel will
still be an ancient 2.4 kernel? Mounting of /proc?

I'd be grateful for any thoughts on this!
