This comes up all of the time, but people still seem to get it
wrong. From the exports(5) manpage,
"A host may be specified only once for
each local filesystem on the server and there may be only one default en-
try for each server filesystem that applies to all other hosts."
The original poster had made two default entries for the /usr
filesystem. This is not allowed.
You are _not_ forced to use the -alldirs option however. This,
/usr/src /usr/obj -maproot=0
Is a perfectly valid exports specification. It will do what you want.
