Generally, yes.
As I mentioned earlier, because the X11 session stuff (as shipped) does
not normally source the .profile, some desktops open xterms etc with
the option to run a "login" shell instead of an ordinary "interactive"
one. Alternatively, they open ordinary interactive shells but then
stuff all the profile setup stuff (the only-needed-once stuff) into
the /etc/bashrc, costing every interactive shell.
The RedHat /etc/bashrc is especially offensive; it reruns all the
profile stuff! Looks at this from a RHEL box:
if ! shopt -q login_shell ; then # We're not a login shell
for i in /etc/profile.d/*.sh; do
if [ -r "$i" ]; then
. $i
fi
done
unset i
fi
Precisely backwards from what should happen. Check your Fedora box.
