At the moment we call exportfs -v every time we check whether an NFS share is active. This happens every time you run a zfs or zpool command, making them extremely slow when you have a lot of exports. The time taken is approx O(n2) of the number of shares. This commit stores the output from exportfs -v in a temporary file and use this to speed up subsequent accesses. This mechanism is still too slow - if you have tens of thousands of NFS shares it will still be painful running ANY zfs/zpool command.

Native ZFS for Linux! ZFS is an advanced file system and volume manager which was originally developed for Solaris. It has been successfully ported to FreeBSD and now there is a functional Linux ZFS kernel port too. The port currently includes a fully functional and stable SPA, DMU, and ZVOL with a ZFS Posix Layer (ZPL) on the way!
$ ./configure
$ make pkg
