Slackware 10 as root
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
adds the enviromental variable, but the next time I
reboot, it's gone! env | more shows it's not there no more.
How do I add an environmental variable permanently
to Slackware 10?
I also noticed that Slackware 10 does not have a
/root/.bashrc or /root/.bash_profile or /etc/.bashrc
So, where does Slackware 10 store it's environmental
variables? Can I create my own /root/.bashrc or
/root/.bash_profile or are these now obsolete and
no longer allowed? I've got some aliases I'd like to
write for ls, cp, etc.

variables will never persist, personally i'd be concerned if they did. if you want a .bashrc, you can create one, they're just not required.

Various ways ...

You could add that to root's
~/.bashrc or ~/.bash_login

You could add it to
/etc/rc.d/rc.local

You could (which is what I'd do) create
/etc/profile.d/pkg_conf.sh
chmod u+x /etc/profile.d/pkg_conf.sh

Why this last technique, even though it appears to be more
work than necessary? It saves me the hassles of touching
other scripts after an upgrade, and the next one, and the
next one .... :}

You can also add it to ~/.profile, and bash will also recognize it. But remember, /etc/profile.d/<name>.sh will be for the system, whereas a ~/.bash_login, ~/.bashrc, or ~/.profile will be for just your user.

Thank you for your excellent advise! My problem
is now solved. I copied out that bash script and
placed it in /etc/profile.d/ and it works perfectly.
I had no idea there were all those scripts in /etc/profile.d/ !
I'm going to have to take a closer look at them, just
to see what I can learn from them. Thanks again!
