I had a look at it now and while it might not be based on RHEL sources it looks like it was built on an RHEL 5 host, judging by the python banner which says it was built with [GCC version 4.1.2 20080704 (Red Hat 4.1.2-50] Most of the standard unix commands are provided by busybox. But it seems to be using glibc and has initscripts in /etc/init.d reminiscent of RHEL, there's even a chkconfig to enable/disable services, no runlevels though. The filesystem layout is much like RHEL and it seems to definitely be a Linux userland so IMHO not very BSD like at all. -tgc
