You might like to think so :-)

When I worked at HP (some time ago now) I did at first think that HP/UX was
SVR4 based: lots of the user-land stuff looks like SVR4.   However, it does
have something of a dual-heritage and I'm pretty sure that  the kernel came
from the BSD kernel originally.

Having said that, HP/UX doesn't look like either.  I do recall, however,
that as I went through different versions (I left at around 11.11i) that the
differences between HP/UX and Red Hat became less and less noticeable, at
least from a user perspective.

There were still gotchas (and presumably still are) but they tended to be
more that things worked better on Linux and on HP/UX.   Going forward from
HP/UX to Linux was generally quite straightforward (once the compiler
toolchain had been sorted out in the build system) but going back did tend
to be frustrating on occasion.

Remember OpenMail?
