I have recently migrated a production server from Solaris to Ubuntu
10.04 Server LTS and have recently been informed that some packages
dealing with libc6 need to be upgraded.  My configuration is a normal
installation with the exception of manually compiled versions of
Postfix (2.7.1) and Dovecot (1.2.11).  Given the following details of
my system's current state, can anyone offer insight into whether or
not upgrading the libc6 packages will break anything?  Thank you very
much in advance.
