=================================================================

This is the Linux Counter summary as of Thu Feb  1 00:43:50 2001

There are 167761 persons registerd.
3023 users have been registered by friends.
There are 89692 machines registered.

I guesstimate that between 0.2% and 5% of all Linux users have
registered with the Linux Counter.
So the total number of Linux users is probably between
3,355,220 and 83,880,500 people.

WHERE LINUX USERS LIVE
The table is sorted by number of Linux users divided by population

Subject: Re: Multibooting 5 OSs => Win98, NT4, Linux, Solaris 8 and Unixware 7 - HOW 
TO???
Date: Wed, 31 Jan 2001 19:58:26 -0500

Things I learnt while tring to setup a multiboot system with linux , win9x
and NT (4 & 5 )

Leave the MBR alone. Do not install any "boot loaders" in there. Most
notably , MS os'es tend to loose it when confronted with   unknown systems.

Do not run the windows NT disk adminstrator after putting in non-MS
partitions - friend of mine spent a 3 day weekend rebuilding his partition
tables after "Disk Administrator" wrote some "signatures" into the drive.

If you mix two or more ms os'es pay special attention to the"c:\ program
files" directory.  One may be running ie4, and you upgrade the other to IE5
. The upgrade replaces files in the c:\program files\common directory . Boot
into the first one  and ... blue screen! Avoid the problem - create a
separate "OS only" partition for each, and make it non readable from the
other : ntfs for nt , fat32 for win98 . If you are usign win2000, the win98
fat32 can be mapped as a logical drive  .

For MS OS'es keep ALL partitions on the same disk. Despite what they say,
they still use the old "DOS" way of assigning volume labels (C:, D: etc. )
. Or when you plug in or remove a drive, the drive assignments will change .

Steer clear of the windows NT boot loader . LILO is your friend . the former
requires a lot of hacks just to get it to boot a win98/nt/linux hdd. The
latter just requies an edit of a text file, and execution of "lilo"  . For
me, the second approach was far easier.

lilo has the capability to switch the hard disk id's . What this means is
this :
Say I have a 20 gig hdd, with win2k, 98 and linux ( hda) . Now I have a
second drive with Me running on it (hdb) .

I tell lilo that when I choose "me", I want it to exchange the drive id's of
hda and hdb. So when I boot Me, it looks as if the second drive is the
master(hda) , and the first is the slave (hdb) . "Me" sees that it sits on a
primary master hard disk  ( Because we changed the id ) and boots up with no
fuss. My friend does the same with NT .

Lilo can also change a partition's id , for example, I can hide the win98
fat32 partition when I boot win2k , and I can hide the win2k fat32 partition
when 98 boots. ( Unhide the one we want to boot, hide the others ) .


Install win98 first . Then NT.  As for the others, I don't have any
experience with them .

But be very carefull with Microsoft systems in a multiboot environment. They
have a habit of doing "helpful" things for you.

    Never heard of this one. However, have you tried with
gdb? If you do display/i $pc and use the nexti and stepi
commands you can step through your code over individual
assembly language instructions.

If you have _some_ control over the hardware, you can discourage the
idiots from powering it off.  Consider:
 a) A case that requires inserting a key to power the machine off.
 b) Putting the UPS inside the cabinet so that the morons can't just
    pull the plug out of the wall.
 c) A power connector that screws into place such that they actually
    require_TOOLS_ to disconnect power.
 d) Putting a drop of epoxy into the power switch so that it No Longer
    Works.

Put those sorts of measures in place to make powering down seriously
inconvenient, and you're 80% of the way there.

Then there's another 20%.

- About 5% can come from ensuring that as many filesystems as possible
  are mounted read-only.  If they're mounted read-only, then the
  reboot won't require fscking them.

- Another few percent can come from not mounting the _big_ filesystems
  right away, as part of boot up, but rather mounting them as part of
  initiating the application.

  That allows you to mount them without them being fscked, should that
  prove necessary.  [It's not recommended, of course.]

- The remainder of the answer is to look to the journalling
  filesystems.  These record, in a journal, where the most recent
  updates were to take place, which means that you don't have to fsck
  the whole disk, but can rather just look at updating the few files
  that the system had most recently touched when moron stuck in a
  screwdriver to short out the reset switch.

  The most mature such filesystem, at this point, is ReiserFS,
  although if you're serving NFS, it is a bit flawed at this point.

  Second most mature seems to be ext3, which augments ext2 with a
  journal.

Yep.  *AND* tar would stop putting file to logfile.

Note that GNU tar will strip the leading '/' from the file names:

'/u01/foo/bar' would be archived as 'u01/foo/bar'.
