my target was to build a server for my files with one or two USB HD formatted in ext3 and the NSLU2.
I tryed for a week with nfs-utils nfs-server etc. but I could't create the condivision on the client. It seemed that all was ok and working, but it didn't work.
So,after a round in this forum I decided to try with the unfs3 package...and it works,with no problems.
So,if you like an easy life and an easy way to obtain a nfs server use UNFS3 and enjoy the openwrt.
Tanks.
