Minimal modification +should be needed to boot NetNuke over PXE (in case you're thinking about it). + +The application itself is written entirely in C, and mostly from scratch. Only one large chunk of code was pulled +from NetBSD's libutil. Linux support may be dropped in order to clean up the code in the coming weeks because FreeBSD's +SCSI subsystem is far superior to Linux's implementation. SUN Solaris support on the other hand may make an appearance +soon depending on the demand to natively wipe their media. + +Just remember that NetNuke was designed to DESTROY DATA. There are no failsafes in place to preserve your precious bits. +The only thing that stands between you and the total annihilation of your data is the "--disable-test" flag. What that +said, please use NetNuke responsibly. Anything attached to the machine prior to running the program will be DESTROYED. + + +TIPS +---- + +1. /usr/bin/nn has no user confirmation routine.
