--- Comment #6 from Dennis Clarke <[email protected]> ---
Could be retrycnt=0 is the default and that causes the behavior :



hydra# mount -o retrycnt=1 pluto:/opt/bulk/passport /mnt/pluto
[tcp] pluto:/opt/bulk/passport: Permission denied
hydra# echo $?
1


Yup.


hydra# tshark -r  out.no_retry   --print

After the ERR_ACCESS the return condition is given.

Works as intended, by default, stupidly in an infinite 60sec loop.
