MINIX 3 has been based on the NetBSD userland since the beginning, I think. That said, always interesting to hear Tanenbaum talk and the dynamic upgrade/checkpointing features sound interesting.
Glad you clarified and said Minix 3; I remember the 90s version had its own userland, and its own C compiler (also written AST), I know this because I hacked on them extensively. Probably the first time I have seen extensive source code, more than a snippet or a *.c file.
"ABSTRACT
MINIX 3 has imported a significant amount of userland BSD code.
The trend began several years ago, but the pace has quickened
markedly. We have already imported NetBSD’s buildsystem, NetBSD’s
C library, the pkgsrc package management infrastructure, and various
userland utilities from NetBSD and FreeBSD."
