This is what I have come up with, and it is WRONG. =) It causes a regression in the case where there are multiple keys of the same name in a map; the patched automounter will always use the last key instead of the first. Remember dealing with this back in February? Fun. I'll keep poking at it, I just wanted to make you aware of the problem. -Jeff _______________________________________________ autofs mailing list [email protected] http://linux.kernel.org/mailman/listinfo/autofs
