dsl@box:~$ su - root
Password:
root@ttyp0[root]# echo $PATH
/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin:/usr/local/sbin:/usr/local/bin:/usr/games:/opt/bin:.
root@ttyp0[root]#

Looks like /opt/bin is there to me.
What root access/login procedure is being attempted?

PATH is set when a login shell happens - if it isn't a login shell, profile won't be sourced.

I believe most distros have root's PATH set differently anyways.

dsl@box:~$ sudo su
bash-2.05b# echo $PATH
/sbin:/bin:/usr/sbin:/usr/bin:/usr/bin/X11:/usr/local/sbin:/usr/local/bin

I see your point, hats....hadn't thought about that.

another variation...
dsl@box:~$ sudo echo $PATH
/sbin:/bin:/usr/sbin:/usr/bin:/usr/X11R6/bin:/usr/local/sbin:/usr/local/bin:/usr/games:/opt/bin:.:.

Right, so you'd want to use sudo su -

Ah, helpful replies guys, thx. On most distros it's the ordinary user's PATH that's more restricted than root's. dsl has a non-login root shell, but it's still root.

I noticed this because /opt/bin isn't in PATH when I open a root shell from the right-click menu (I only rarely type su - on dsl) and it might be useful if binaries linked into /opt/bin could be found from any type of root shell, just like binaries in /bin whatever, hence found by other apps running as root that look in PATH.

Root should be able to find anything in PATH that user dsl can, yes?
