I have a server running Ubuntu Oneiric 11.10, which I cannot upgrade.
I've followed instructions given here
to upgrade bash. However, I noticed that these commands also upgrade libc6 among with other libraries. If I'm correct with my understanding, libc6 is a shared library used by many programs, including apache and mysql.
My question: what are the consequences of running the newest libc6 on an older system? Are there any incompatibilities?
