I have no idea what I'm doing wrong:
/etc/sudoers.d/emelfm2.sudoers

with
user ALL = NOPASSWD: /usr/bin/emelfm2 also tried with (%) in front and with the line in "01sudo"

and the emelfm.desktop with:
Exec = /usr/bin/sudo /usr/bin/emelfm2 => the app processes for a little while than it just quits.
Exec = osso-xterm "sudo emelfm2" => it asks for a password...

i tried sudo gainroot, passwd, set a new password and then replaced the "NOPASSWD" ... didn't work.

What am I doing wrong?
