While playing around, I discovered a folder in my
$PATH that I did not recognize:
$ echo $PATH /usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games $ ls /usr/lib/lightdm/lightdm gdmflexiserver
gdmflexiserver is used to start another X session or some such. Is this part of the default package? I don't see the use for it for a normal user, and it seems odd to have in one's path, especially when it is just for one program. Why would it not be under one of the other paths in that case?
