[CentOS] Odd failure of smbd to start from init.d - CentOS 5.4

[Brunner, Brian T.]

WTE?
do
printenv > dot.slash.env 
add to /etc/init.d/smb
printenv > ~/init.d.smb.env
then execute /etc/init.d/smb

There has got to be a difference between the two environments causing
identical scripts to behave differently depending on how they're
executed.

unless

PATH searches . before other directories, *and* there is a file in
/etc/init.d or ~ that causes different behavior.

(hint, make sure . is last in your PATH, if it's there at all.  Security
breach can exploit a misplaced PATH . )
