Comment 4 for bug 790043

It's worth noting that the bash completion scripts are being started twice when logging in either via a tty or bash's (-l) option. The fault with that is that most systems are checking the shell in /etc/profile.d/bash_completion.sh to see if its bash and then proceeding to call the bash_completion itself, neglecting the fact that bash calls /etc/bash.bashrc anyway which will do the same thing. Lucky for me i rarely log in via tty, im usually in xterm and dont use the (-l) option, but even with one go, those scripts that are being executed are installed into /etc/bash_completion.d/ by the various packages that feature specialized completion. Though we can't blame them because this is exactly what was intended in the first place. The tag is passed back to bash to address startup script execution times in order to speed up this it is going to have to consider the existing scripts out there already. For now maybe there is some way to cache this in a way that would be efficient for both resources and users?
