Bon comme dab j'ai le réflexe de poser des questions avant même de chercher un peu les réponses alors voici un résumé de ce que j'ai trouvé en guise d'excuses...
mais j'ai toujours une zone sombre entre freeBSD et OpenBSD ...
1)
Linux is a clone of UNIX written by Linus Torvalds, a student in Helsinki,
Finland. At the time, the BSD sources were not freely available, and so Linus
wrote his own version of UNIX.
Linux is a superb example of how a few dedicated, clever people can produce an
operating system that is better than well-known commercial systems developed by
a large number of trained software engineers. It is better even than a number
of commercial UNIX systems.
Obviously, I don't think Linux is as good as FreeBSD, or I wouldn't be writing
this book, but the differences between FreeBSD and Linux are more a matter of
philosophy rather than of concept. Here are a few contrasts:
Table 1-1. Differences between FreeBSD and Linux

In summary, Linux is also a very good operating system. For many, it's better
than FreeBSD. It's a pity that so many people on both sides are prepared to
flame each other.
2)
Linux is SysV-flavored (barely); FreeBSD is BSD-flavored (definitely).
3)
Linux tends to be more cutting-edge and trendy, and tends to work with more
hardware (to some degree), partly because of the "arrangements" made with
vendors. FreeBSD requires that source code be freely obtainable for
(nearly?) all it's parts . The hardware that _is_ supported tends to be done pretty robustly.
4)
Remember: FreeBSD is not a clone! Linux is! i.e. FreeBSD is Unix(r)
5)
Please, this isn't a "My OS is better/bigger than your OS"
discussion/arguement/whatnot, and I think its delved a lot more off the
original thread.
Both linux and FreeBSD have their good and bad points, and unless you are
going to constructively point them out, don't say anything.--

aware of when maintaining a Linux box.

Est-ce que quelqu'un peut me faire une brève comparaison entre NetBSD, FreeBSD, OpenBSD et Linux ? (tous ca a un www. .org, avec le code source libre)
entre FreeBSD, OpenBSD, Linux, et j'ai déjà découvert que le logo officiel
est respectivement un daemon avec des baskettes, un daemon avec une auréole, un pingouin avec un gros derrière (dixit http://www.de.freebsd.org/de/gif/bsd/userfriendly.html )
Mais et au niveau du noyau ?
Est-ce que Linus c'est inspiré d'une de ces distribution de BSD ?
