On my Fedora 14 developer machine I can add a sharedAliases.sh file to /etc/profile.d -- both my user and root user then have access to the shared aliases.
Switch over to remote CentOS 5.7 machine and what appears to be the exact same config, no dice, root user does not have access to the shared aliases.
This may be due to the fact that I SSH into the CentOS box, not sure. At any rate, the lame workaround has been to copy shared aliases into root user's .bashrc as it's the only way I've been able to get desired prefs into root (yes, I know I should sudo, but have been rolling with su for years).
Ideas appreciated, would prefer to not have to duplicate aliases if possible.
