Hi Baptiste,

How is this different from posix.unistd.exec in the luaposix module?
Wouldn't it be better to add this to the existing posix.unistd namespace
in lposix.c?  exec does not seem FreeBSD-specific.

I have a related question: this week I wrote some FreeBSD-specific lua
modules wrapping some system calls like sysctl(2) and cap_enter(2).  How
do we want to organize the flua namespace for such things?  Should we
have a freebsd.sys namespace for system call wrappers?  I would then put
bindings for FreeBSD libraries under freebsd.* or freebsd.lib.*, so we
could have freebsd.lib.procstat, for example.
