Dont go blaming UNIX for the installation problems of Linux. Having
just done a round of installations (MacOS X Server, Solaris 7 and
SuSE 6.1 to replace a RedHat 5.2 installation) I can say that Linux
is unique in the pain it inflicts.
Neither RedHat nor SuSE are well suited for complex installations by
someone without Linux experience, and their 300-400 page manuals are
useless for the actual installation. In SuSE's "Installation - the
details" section, there are NO details on either parititioning large
disks nor package installation. If you have a large disk with another
operating system, and you want to do something semicustom, you better
know about things like the /boot partition from previous Linux installs,
because the manual isnt going to give you any useful inline information.
Package installation on SuSE is the worst, allowing you to select more
than one configuration concurrently and leaving you with the impression
that you are adding or replacing elements in the list rather than adding
or replacing actual packages with the Add and Replace buttons. The
markers [i] and [X] are not explained anywhere in the installation text,
but in another chapter. The most curious thing is that the [i] appears
anywhere, as it says these packages are already installed, when in fact
absolutely nothing is installed on the system. The package sets are not
described anywhere. Selecting everything results in conflicts, which
is unique in the 20 or so operating systems Ive installed over the years.
I suspect this is due to the inability to differentiate the core system
from additional packages. SuSE didnt seem to give a lot of control over
which services were started automatically, so I ended up with a huge
number of processes, including four name servers even though I told it
to use another machine for name service. Also, whats the deal on swap
partitions? I thought that 2.2.x was supposed to support swap partitions
over 128M yet the SuSE manual and partitioning software still have
warnings about trying to use swap files over 128M.
As I recall, Redhat was different. Partitioning was still worse (why
Linux cant allocate a single BIOS partition and provide the usual 8
slices that other UNIX systems provide is beyond me) but the rest of
the installation was smoother, you had more control over which services
ran, and the LILO configuration allowed me to reference the nextstep
partition from the installation routine instead of hand editing the
lilo.conf file and reloading it (something a novice would have to
dig to find out about with SuSE.) I had to edit the /etc/modules.conf
file by hand to get my Turtle Beach Pinnacle sound card to work as the
UI based configuration just plain didnt work - this wouldnt go over
well with a novice either. I havent configured this card with SuSE yet,
so I dont know if thats going to be easier or not. I got the extra
stuff like the PowerTools, only to find that when I wanted to install
a package I got errors about missing packages, and had to fish them
out of the same disc by hand rather than being allowed to select an
"install all dependencies as well" button. The commercial X server
should also be avoided at all costs if you have a Matrox Millenium
card. I couldnt select valid display modes for my monitor and when
the screen saver activates the server trashes itself. The XFree86
stuff worked flawlessly, though the configuration is still not well
setup for a novice.
I havent installed Slackware in years, but I remember is being much
easier to install than either SuSE or Redhat. Unfortunately its been
too long to quantify why.

does anyone know of any overviews of how GUI's work internally.
preferably something i could download for free. I was naturally
thinking of X, but i couldnt find any info i could get free- the
opengroup (who controls the X spec) wants to charge $$$$ to download

Will this work if the offending programs do not contain debugging
information?
You can find out which program dumped the core just by running
$ file /usr/lib/rhs/control-panel/core # and so forth

Subject: Can't boot linux anymore from HD
Hello,
last saturday I suddenly could not boot Linux from the HD anymore. When
booting, LILO begins the boot process correctly, but after that first
line "Loading linux..........." is written to the screen, the PC reboots
immediately. However, it is still possible to boot from diskette (which
takes an eternity), and LILO also lets me boot into DOS correctly (DOS
is on my /dev/hda partition). After booting from diskette, I seem to be
able to work absolutely without problems. Also, I don't remember any
essential problems during the last sessions or the last shutdowns before
the problem appeared.
I'm using Debian Linux 2.0.34 on a P100 PC.
I would highly appreciate any suggestions concerning possible causes of
the failure or any advice at which parts of the system to look for
fixing the problem.
Thank you,

the point being that since the original vt100 only had 24 line mode
there are no `how many lines have you got?' escape codes for it.
anything that resize could use would be an extension to the vt100
codes and therefore not covered under the rubric of vt100.

yes. this is correct. under linux, in any flavor, the modem will

We have UNIFY DataServer 6 running on

and are quite pleased with it. They are
busy porting
their Vision tools to Linux, too.

Unfortunately for this argument, MS includes what they call a license
withtheir software, which claims that you must agree to the terms of the

Now, one could argue that the terms of this "license " are invalid as it
tries to bind the purchaser to terms of an agreement after the fact.
However such an agreement is binding on the party that wrote it, even if
not on the party that received it, since they presumable knew what they

You can run any glibc on any 2.x kernel. You may need to have 2.2.x kernel
headers in order to compile glibc-2.1.x.
Apparently there will never be a glibc-2.0.7 release, but the pre-release
sources can be found at ftp.us.kernel.org/pub/software/libs/glibc. (Those
outside the USA should substitute their appropriate country code for "us"
in the hostname.)

Denormalization is something sane folks do to increase performance,
not to avoid the need for a real database engine.
If you've denormalized checking balances into thirty tables,
don't have atomicity, and an update dies half-way through
updating these tables, which balance do you trust?
Or if another process reads these tables when processing
an order, which balance should it use if they don't all
agree?
I suppose you can start implementing all sorts of cross-checks
to help you unwind afterwards but...
Why bother? Why not use a transaction-based db in the first
place?
