1 ===============
1
1 This section aims at presenting some systems and pointers to
1 documentation. It may help you addressing particular problems reported
1 by users.
1
1 Posix-conforming systems (http://www.opengroup.org/susv3) are
1 derived from the Unix operating system
1 (http://www.bell-labs.com/history/unix/).
1
1 The Rosetta Stone for Unix (http://bhami.com/rosetta.html) contains
1 a table correlating the features of various Posix-conforming systems.
1 Unix History (http://www.levenez.com/unix/) is a simplified diagram of
1 how many Unix systems were derived from each other.
1
1 The Heirloom Project (http://heirloom.sourceforge.net/) provides
1 some variants of traditional implementations of Unix utilities.
1
1 Darwin
1 Darwin is also known as Mac OS X. Beware that the file system
1 _can_ be case-preserving, but case insensitive. This can cause
1 nasty problems, since for instance the installation attempt for a
1 package having an `INSTALL' file can result in `make install'
1 report that nothing was to be done!
1
1 That's all dependent on whether the file system is a UFS (case
1 sensitive) or HFS+ (case preserving). By default Apple wants you
1 to install the OS on HFS+. Unfortunately, there are some pieces of
1 software which really need to be built on UFS. We may want to
1 rebuild Darwin to have both UFS and HFS+ available (and put the
1 /local/build tree on the UFS).
1
1 QNX 4.25
1 QNX is a realtime operating system running on Intel architecture
1 meant to be scalable from the small embedded systems to the hundred
1 processor super-computer. It claims to be Posix certified. More
1 information is available on the QNX home page
1 (http://www.qnx.com/).
1
1 Tru64
1 Documentation of several versions of Tru64
1 (http://h30097.www3.hp.com/docs/) is available in different
1 formats.
1
1 Unix version 7
1 Officially this was called the "Seventh Edition" of "the UNIX
1 time-sharing system" but we use the more-common name "Unix version
1 7". Documentation is available in the Unix Seventh Edition Manual
1 (http://plan9.bell-labs.com/7thEdMan/). Previous versions of Unix
1 are called "Unix version 6", etc., but they were not as widely
1 used.
