You probably wanted to ask about exec(), though... the answer for exec() is "it uses the brand on the exec()'ed binary to decide which call table to use". This probably means that you are running into a problem with an unbranded Linux binary being run from another Linux binary... alternately, you might be confusing the path prefix lookup for branded binaries, which causes an path search to look in the /compat/linux directory before looking under /, if what is being run is a Linux binary. -- Terry To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
