Yes, it means exactly that. Unfortunately, you cannot pull in arbitrary linux libraries and expect them to work because many of them make system calls that are unimplemented in the OpenBSD emulation code. I tried to use the Debian libraries on a dual boot system since it seemed wasteful to install a second set of linux libraries and ran into this same problem. Look at /usr/src/sys/compat/linux/linux_syscalls.c to see what is unimplemented; there are about 30 of them. If you want to stray from redhat_base, you will make it difficult for yourself. -- Mark
