autofs cannot mount remote directory path with space

Hi,

I was wondering if you were still having this problem?

Thanks
chuck

Yes, I am still having the same problem. I just confirmed it, running
fully updated 8.04.3 on both NFS client and server. It's quite clear
from the source code what the problem is.

Hi Mike,

Patches are always welcome.

Thanks
chuck

Hi Chuck, I am definitely not able write a patch in any sense.... I
can read the code but figuring out what to do to fix and test it in
the context of the whole program and OS is another issue entirely!
