You can set up your ~/.bash_profile to source your ~/.bashrc:
Code:
if [ -e ~/.bashrc ]
then
source ~/.bashrc
fi
...and then set up your ~/.bashrc to source your /etc/profile:
Code:
if [ -e /etc/profile ]
then
source /etc/profile
fi
That should make sure all settings are always set, no matter how you log in.
