I would say the first boot record of teh Linux parrtition. If you install it to
the master boot record it will wipe out the NT loader, which as far as i know is
required to load NT.
The boot.ini for NT can be edited to point to LILO to boot Linux, but I would
recommend a boot manager like System Commander. It will automaticly detect both
NT and Linux and set up boot entries for them, but it only works if LILO has not
been installed to the master boot record.

Netscape, on Linux and on Windows, reads a large number of files at
startup, in a fashion that jumps all over the place. You can make
Netscape start in about half the time on Windows (and I suspect that
this would work on Linux, too) by writing a program that does all the
I/O Netscape does to start, but in a saner order, and then launches
Netscape. That starter program gets all the data into the cache, so
that Netscape's erratic reading of it doesn't hurt.

unfortunately DLL's and other resource type files can be fairly

Using an underscore is nonsense too. Fix the danged compilers to allow
spaces in variable names. (Note: no, this does not create a lexical
analysis nightmare).

Subject: Linux SCSI AIC7xxx driver
Date: Tue, 29 Dec 1998 09:32:42 GMT
Hi,
I've got a little problem.
I have a Adaptec AIC-7770 adapter and hard disk. I made a partitons on it
under 2.0.35, and leter a I've upgraded to 2.0.36. Both of them (2.0.35 and
2.0.36 has the same SCSI configuration).
Under 2.0.36 fdisk display errors:
======================================================
Using /dev/sda as default device!
Command (m for help):
Disk /dev/sda: 255 heads, 63 sectors, 274 cylinders
Units = cylinders of 16065 * 512 bytes
Device Boot Begin Start End Blocks Id System
/dev/sda1 1 1 64 513008 83 Linux native
Partition 1 has different physical/logical beginnings (non-Linux?):
phys=(0, 1, 1) logical=(0, 0, 33)
Partition 1 has different physical/logical endings:
phys=(500, 63, 32) logical=(63, 221, 30)
Partition 1 does not end on cylinder boundary:
phys=(500, 63, 32) should be (500, 254, 63)
/dev/sda2 502 64 80 123904 82 Linux swap
................
========================================================
,but everything is clear under 2.0.35.
It's strange but under 2.0.36 system is working ok, If I hadn't run fdisk
I would have never discover this error.
I attached dmesg files from 2.0.35 and 2.0.36
What should I do?

I whole heartedly agree with your last point, i.e. that the system
must use as few dependencies as possible during boot. This keeps
the system small/fast/reliable ... Many small systems don't need
config management as things rarely change, so you are right they
should not be burdened with code that is meaningless to them.
However, larger systems/sites/networks are another beast entirely
and tools like YP/NIS become increasingly valuable as things scale up.
While one can define new maps in NIS, this is typically not done
for application and user configuration information. I'm not sure
if NIS could be contorted to perform all the functionality desired.
Don't get me wrong, I think it's great stuff and I can't tell you
how much time NIS has saved me over the years! I have never tried
to setup maps on a per user basis, can NIS do that?
Anyhow, if a users configuration is stored under thier $HOME
it will always be available on any system that mounts/automounts
there home directory. Actually this brings up a couple of
problems. Sometimes that's what they want, sometimes they might
want a different config while running an app on a different
system. The later case could be handled by judicious use of
a config path variable. Another problem is a user might not
have thier $home mounted on another system. A config service
could publish the config info an make it available across the
network. Hmm, it's tempting to push the config info down
into a $OS/$Version/$Arch/$Hostname hierarchy.
I was thinking about handling this in a different manner, i.e.
making the flat files be either "data" or "executable". In
the first case a particular format is adopted. In the second,
the executable could be run and it's output must be in the
desired format.

Actually the name is for a directory so must be a valid file/directory name.
"user store" would be valid, but makes it hard for those not versed
in shell subtlty. So I'm still favouring .userStore as the top
level of the users persistent storage space for applications configuration
and other persistent application data related to the user. If anyone can come up
with a better name, I'm still listening.

Well you might want to look at my product, IDKSM.
http://www.miraclec.com/software.html
It meets most of your requirements that you list above. I'm am sorry to
say that the current version of the Indexer only works in (please don't
beat me) Windows.
The runtime engines are available as Delphi code, Windows .DLL, Java
.class files for use in applications, a Java applet for use in web
pages, Windows web server CGI, and a Java Servlet CGI. In your case you
would be able to use the Java version on your Linux machine.
Fear not however because I am indeed working on creating Linux versions
of the runtime engine using Free Pascal. Once that is complete and after
the next release cycle I might start the work on the Linux version of
the Indexer. The Indexer will most likely be Gnomeified. :-)
The other down side is that it isn't free. It's cheap but not free. The
Indexer is shareware which costs $50 to register. The runtime engines
are free and can be used and distributed as much as required. The
Indexer can not be distributed.
I know you stated that you are not expecting stellar performance but I
think you would be very surprised and pleased with the speed of IDKSM.
Demos of the applet using the Java Servlet running on my Linux host
using Apache can be found on the web page listed above.
Hope this helps. :-)
