I'm also not totally satisfied with the answers given so far, e.g.: | Q. Do standard programs run under Debian GNU/kFreeBSD using the Linux | Compatibility Layer? | | A. No. Q. Why not? :-) Oh, And Petr: I would rephrase that question back to "Do _Linux_ programs run under Debian GNU/kFreeBSD using the Linux Compatibility Layer?" I have no idea what you meant with "standard" programs.
So rephrase question in a different way. Q: Which syscall kernel interface is used by binaries compiled for Debian GNU/kFreeBSD ? A: The native FreeBSD one. Q: Is it possible to run FreeBSD binaries under Debian GNU/kFreeBSD kernel ? A: Yes, please just use the full chroot with FreeBSD libraries. Q: Is it possible to run Linux binaries under Debian GNU/kFreeBSD kernel ? A: It is untested, but it should be, as long as standard FreeBSD Linux Compatibility Layer is sufficient. Some symlinks might be missing. May be even linux-i386 chroot under kfreebsd-amd64 and kfreebsd-i386 works. At least simple static Linux binaries run under our kernel, but I didn't test it more, like debootstrap --arch=i386 sid ./linux-chroot http://ftp.de.debian.org/debian Petr
