Preliminary support for Interix, a UNIX-like environment for Microsoft Windows 2000, XP, and 2003, has been added to NetBSD’s Packages Collection. The support is still new and incomplete, but it is now possible to bootstrap pkgsrc and install simple packages. Interix is part of Microsoft’s Windows
Services for UNIX package. See Todd Vierling’s email to the tech-pkg mailing list for more information.
