DG-UX was a pretty generic SVR3
User space was generic. But the SVR3/88K kernel was a heavy rewrite.
LCC did a lot of work with DG adding stuff too it -- it was very well done
by the DG team in NC. The memory and FS was well integrated.
So read()/write()/mmap() all shared the same cache like SunOS? In SunOS the
only things not in the page cache were directories and inodes. All data
pages had one, and only one, place to be (ZFS broke this in Solaris,
which has always blown my mind).
