Titolo: Linux vs. FreeBSD vs. NetBSD

Quanto mai IT, di questi tempi:
---------------------------
Many people ask the question "Which is better?  FreeBSD, NetBSD,
OpenBSD, or Linux?"  Up until now, not many people are willing
to answer thoroughly and give reasons.  I, being a brave soul,
am.  This mini-FAQ lists the most significant differences
between Linux, NetBSD, and FreeBSD in a fair and evenhanded
manner.  Permission is given to redistribute this mini-FAQ
freely, with attribution.  If anyone wants to take the burden
of posting it periodically on the appropriate newsgroups, be
my guest.
This is based on a message I wrote some months ago.  I've
tried to update it substantially to reflect the changing
nature of x86 OS's.
-------------
Q) Which is better?  NetBSD, OpenBSD, Linux, or FreeBSD?
A) NetBSD is the best of the three because of it's superb
error handling capabilities (this is the "Net" referred to
in the name).  With NetBSD, it's almost impossible to make
a mistake, either in installation, or operation, because the
system will "catch" you as you "fall".  NetBSD works on a
wide range of processors, including the Intel 386, 486, and
586, the Sun, Sparc, SGI, MIPS, Macintosh, Motorola 6809,
Krupf, ADC Kentrox, Whirlpool, Amana, Zilog Z80,
Timex-Sinclair, and the Braun.  Currently, the NetBSD team
is devoting all of their energies towards finishing the
all-important IBM RT port.
Linux is the successor to an operating system called "Minix".
Linux was developed by Linus Pauling, a Finnish communist.
Linux tries to uphold traditional Marxist values in several
ways; firstly by using GNU tools from the FSF foundation
wherever possible.  The Linux kernel is developed by committee,
and the operating system reflects this:  rather than having one
"init" process which fathers all others, a group of co-resident
processes with equal powers are created simultaneously.  "Kill"
commands are treated as formal protests.  Linux networking has
come a long way since it's implementation, and there is no truth
whatsoever to the rumor that sudden losses of IP connectivity
are in any way related to future plans to limit users to 1.5
hours of SLIP or PPP unless they send in the registration fee.
FreeBSD was a radical offshoot of the Linux project; you could
consider it to be of the Trotskyite school.  FreeBSD supports
an extremely wide range of PC hardware, as long as it was
obtained at less than cost.  FreeBSD is used by Amnesty
International and many other human rights organizations.
FreeBSD supports every peripheral available for the IBM PC
except the ones you have.  The FreeBSD team was actually
responsible for porting  "Doom" to Linux, in a successful
effort to slow down constructive work by distracting the
central committee with frivolous games.  FreeBSD has the
nicest installation of any of the x86 unices -- you install
the boot disks, which then initialize the modem and call
Jordan "Perky" Hubbard, who then comes to your house with the
rest of the disks and completes the installation.  The FreeBSD
CD-ROM plays various Nick Cave and Tom Waits songs Jordan is
known to be fond of.
386bsd was written by Bill Jolitz in a fit of pique.  It was
based entirely on Sun's widely-respected "Solaris" operating
system, as revenge against Sun's Bill Joy, who rudely chose a
name with the same initials as Jolitz.  A new version of 386bsd
will be released very soon.  Unfortunately, it will only run on
386es, and thus is unsuitable for anyone with a 486 or Pentium.
486bsd should be released "sometime in 2138," according to
industry insider James Monroe, Sr.
DID YOU KNOW?
=============
1) The Free and Net BSD teams split up in the year 1632.  The
cause of the split is uncertain, but it seems to have something
to do with someone named "Janice."  They still get together for
drinks occasionally, and remember old times.  Every so often,
after tying on a few too many, they end up waking up next to
each other and feel ashamed over their night of pleasure.  The
kids still blame themselves.
2) The Linux kernel has actually not changed at all since January,
'94?   Linus just increments "version.c" once every 48 hours and
unleashes the "change" on an unsuspecting Internet, bringing FTP
servers to their knees.  A book, "The Design and Implementation
of the Linux Operating System," by Gary Marshall James T. Kirk
McUsenet, was rejected by Addison-Wesley on the grounds that they
didn't feel the public was prepared to purchase a book written
on looseleaf paper with diagrams in crayon.
3) All three systems claim to be "POSIX" compliant.  However, the
POSIX people have denied knowing anything about it.  Scuttlebutt
in the industry is that POSIX will soon be outdated, and will be
replaced by GNOPIX, a FSF standard which implements the TOPS-20
operating system in Scheme.

Non l'ho letto tutto perchè non mi andava :)
Cmq io la vedo cosi (ma non solo io)
FreeBSD: il + diffuso e con una maggiore disponibilità di pacchetti
OpenBSD: il + sicuro
NetBSD: boh :)
Linux: può essere tutt'ettre :)

 dump(8) doesn't hang when dumping mounted filesystems. You are refering
 to a genuine bug which was fixed some time ago.
 However, in some rare occasions, dump can save corrupted data when
 saving a mounted and generaly highly active filesystem. Even then,
 in 99% of the cases it doesn't really matter because the corrupted
 files will get saved by the next incremental dump.
 Come on, who REALLY expects to have consistent backups without
 either unmounting the filesystem or using some snapshot techniques ?

[ Pop è il maintaner di dump(8). ]
E, Andrea Arcangeli dice, riguardo a quanto espresso da Linus:
 just to clarify, the above implicitly assumes the fs is mounted
 read-write while you're dumping it. if the fs is mounted readonly or if
 it's unmounted, there is no problem with dumping it. Also note that dump
 has the same problem with read-write mounted fs also in 2.2, and I guess
 in 2.0 too, it's nothing new of 2.4, it just gets more visible the more
 logical dirty caches we have.
