Well, the Aeleen Frish's "Essential System Administration" uses
the presence or absence of /etc/inittab to classify machines. It's
pretty goot all in all. I think another indicator of a kernels true
lineage is whether the group ownership of a file is inhereted from the
containing directory without the sgid bit being set. This use of the
sgid bit is for BSD compatiblity.
BTY, I believe HP-UX 9.x is SRV3 derived whereas HP-UX 10.x is
SRV4. HP-UX does have a bunch of BSDisms though. (Not enough for me
thoguh. ;-)
