>Release: FreeBSD 4.5-STABLE i386
>Organization:
iMach, Ltd.
>Environment:
N/A
>Description:
pccardd does not contain an option to exit immediately after probing
the cards. This is neccessary in low-memory embedded environments
where the overhead of pccardd running after the initial probe is not
wanted or needed.
>How-To-Repeat:
N/A
>Fix:
Patch is attached. I am currently re-applying this to my source tree
by hand after each cvsup. I have tested this and it works (dozens of
486 8MB wireless systems floating around with this patch).
I would appreciate it if a maintainer would look at this and possibly
apply it to the -STABLE tree, if possible.
(Both man page and source file patches are below)
