CD permissions

[JJ Neff]

You do not have to actually log in as root to run XcdRoast, you have to have
the equivalent root authority.  SO you can run Xcdroast form a cmd line with
"sudo xcdroast"  granted you are in sudoers file (man sudoers, man visudo, man
sudo) or "su" then enter root password and run xcdroast.  If that is what you
meatn you were doing then skip to next part:-)

XCDroast has on newer instances a non-root user mode that can be enabled.  I
clicked the selection box to disable user mode and now I can;t figure out how
to get it back :-)!

But if you check your Xcdroast there may be atoggel to chang to regular user
mode which changes permissions of the correct things so teh cdwriter group can
use xcdroast.  Now that I clicked the do not use on-root button I have to be a
root equiv as well.  Wish I could figure out how t get that back, BUT now I'm
playing with K3B since I am using KDE here...
