6.7 Systemology

This section aims at presenting some systems and pointers to documentation. It may help you addressing particular problems reported by users.

The Rosetta Stone for Unix contains a lot of interesting crossed information on various Unices.

Darwin

Darwin is also known as Mac OS X. Beware that the file system can be case-preserving, but case insensitive. This can cause nasty problems, since for instance the installation attempt for a package having an `INSTALL' file can result in `make install' report that nothing was to be done!

That's all dependent on whether the file system is a UFS (case sensitive) or HFS+ (case preserving). By default Apple wants you to install the OS on HFS+. Unfortunately, there are some pieces of software which really need to be built on UFS. We may want to rebuild Darwin to have both UFS and HFS+ available (and put the /local/build tree on the UFS).

QNX 4.25

QNX is a realtime operating system running on Intel architecture meant to be scalable from the small embedded systems to the hundred processor super-computer. It claims to be POSIX certified. More information is available on the QNX home page, including the QNX man pages.

Tru64

The documentation of several versions of Tru64 is available in different formats.

Unix version 7

Documentation is available in the V7 Manual.
