This simple patch adds support for the BSD "growfs" command, so you can grow BSD filesystems [in theory -- see below]. It also adds a new optional group called "ufsutils" which indicates if the libguestfs API supports the guestfs_ufs_growfs call, since it's not available on Fedora. (http://libguestfs.org/guestfs.3.html#availability) I tested this on Debian, and although we appear to be invoking the growfs.ufs command correctly, the growfs command contains a bug. It appears that Debian doesn't implement the BSD DIOCGSECTORSIZE ioctl, which means that growfs on Debian always dies with this error message: bogus sectorsize: 0 This appears to be a Debian bug. Someone else can do a bit more investigation on that one and file a bug if necessary.
