uncompress the kernel??? why?
your gonna recompile it anyway no?
do you have the configfile and source for your current kernel?

But I still don't see how this will help you. For example if you screw
up "root" then how is "root2" going to do you any good? I mean "root"
would already be screwed, right?
I'm curious not being smart about it.

I can't disagree with this; I've never been able to force myself to use
Amaya for more than ten minutes at a shot.
It seems vastly more satisfactory to type up web pages using a text
editor, and remedy missing tags and otherwise tidy the code using
Dave Raggett's "HTML tidy" utility.
Of course, for anything nontrivial, you _really_ need to have some sort
of clear design in mind, and either head to:
a) Using something like DocBook, which buys you indexing and
sophisticated page interlinking "for free," as well as considerable
options for validation, or
b) Writing code that "compiles" information into HTML, in much the
same way that GCC compiles C code into assembly language.
Otherwise, you're left tuning things by hand, which is rather analagous
to the assembly language hacker in a world of high level languages.
Assembly language hacking can be _quite_ acceptable, supposing you have
a sufficiently sophisticated set of macro programming tools to help you
do it _well._
That actually seems to be a rather good analogy; given a potent macro
rewriting system (or equivalent thereof), you can do powerful things
with HTML. Whether that beats those that use higher level tools is
somewhat arguable...
Amaya fits in as something resembling a "verifying design tool." It
forbids creating anything that doesn't look like valid HTML; that's
not necessarily helpful if you're trying to do editing that is more
than merely cosmetic.

Would you be more impressed with the contention that web content needs
to be of a form that people with handheld PDAs, cell phones, and such,
can cope with?
My brother and I were sitting in a theatre waiting for a movie to
start last week; had the entertainment of doing a bit of "webbing"
on his Palm V with cellular modem.
It was interesting that practically _anything_ that tried hard to
do "k001 grafix" was utterly unreadable, whilst the same web pages
that are readable with Lynx and w3m (Lynx is _NOT_ the only text-based
web browser, not by a long shot!) were nicely readable on the Palm V.
I'm certain that the differences will be even _more_ pointed when
people use cell phones with slightly smaller displays.
You may argue that it is irrelevant, and that "cellular web will
never sell." I would suggest reserving judgement...

Anonymously or as a user? As a normal user you should be able to at least
read it.
Although, I had trouble accessing a mounted Win95 (FAT16) drive from
commandline ftp in Win98 due to the mixed up case of directories and files
or some sort of Windows shortcuts. I particularly had trouble accessing
windows/Desktop or windows/desktop or a download or Download directory
under that regardless of what case I used for directory names in the path.
But I had no such trouble from Linux, so I finally gave up and copied the
file to my home dir and transferred it from there.
>do I have to chmod/chown on the /win98?
Options for mounted drives are set in the mount command or /etc/fstab.
So see 'man mount' and 'man fstab'. I would think that the default would
be readable (but not writeable) by all normal users. But for anonymous
users to see anything it would have to be mounted under the ftp directory
tree (probably not a good idea, but I do that with cdrom).
>is it a /etc/ftpaccess file fix?
I am not familiar with that file (haven't used it).

Yup. Fine.
Note the system does NOT use the name. It uses the UID (in this case 0)
for most things. Thus if you do an inverse lookup, it will report back
root, not root2 since root is the first username with uid 0.
There is no point in giving it a new home directory, since it is
identical to root.

I agree with that. Although I had a very happy surprise about two days
ago. My parents bought a computer with a 56k on-board winmodem! When I
installed Linux on that computer, it didn't detect the modem. After
reading some howtos, I found a driver for that modem and it's working
with no problem at all. It's a PCTel modem.

Tom's RootBoot, the most Linux on one floppy... incredibly useful for
rescuing systems, and much quicker than mucking with all the problems that
bootdisks are heir to in most cases. It's not a good choice for booting a
fully functional Linux system from floppy, though.
As for your problem, it sounds like the filesystem you've mounted as /
isn't actually the right one. The kernel mounts whatever you told it was
the root partition, then executes /sbin/init . If you've rdeved the
bootdisk to /home, then things will not work at all. If filesystem
corruption has scribbled all over /sbin/init, then you'll get the same
error, but that's a little rarer.

I would never be one to argue in favor of ANYTHING M$ but I would
strongly argue against "non glitz" if that means text and nothing
but text.
That is like those who would like to keep computers stuck at CLI.
CLI has its place but, damn, what a waste of graphics capability,
CPU power, and software development to toss it all and just go
text. Besides, it is a fact that an image sticks in the mind
better than text.
Try and read scientific papers with no graphics (no gel images,
no bar graphs, pie charts, plots, etc). No journal prints text only.
They ALL use graphics because it enhances understanding manyfold.
PDAs and god-damned cell-freakin' phones will just have to develop
graphics capabilities or be made to work as well as lynx does
(better yet, toss the damn cell phones in the trash and pay attention
to the freakin' road, or the person sitting across from you, or the
movie...but I digress).
Hell, if all you need/want/think is THE way is ugly, boring
text, then dump your PentiumII/III/PowerPC and hook up an 8088
or TI-99/A and a 640x480 monochrome screen. They can handle text
just fine. Anything beyond those is a waste of processing power,
graphics power, and money.
Things change. Capabilities increase. It is sick and wrong not
to take advantage of it. That is NOT to say that web designers
should waste bandwidth with pointless cute images and animations.
They should NOT stray or fear using graphics, images, whatever
such that it adds to what they are presenting or clarifies
what they are presenting.

I suppose so. I guess I'll give ifconfig a try...any idea if it

Oops, misunderstanding time. OSS, confusingly enough, stands for two
things: The Open Sound System implementation that's distributed as source
with the Linux kernel, and the commercial OSS sound drivers that you can
buy for $20-30. Most of the Linux sound drivers attempt to use the OSS
standard, and even the ALSA project has an OSS compatability layer. OSS
generally means the free implementation unless it's qualified with
"commercial".
Heavyweight? On my desktop:
es1371 27012 1 (autoclean)
ac97_codec 6692 0 (autoclean) [es1371]
soundcore 3588 4 (autoclean) [es1371]
...works out to about 37K or so of kernel memory, plus a 64K buffer is <
128K. The commercial OSS drivers are quite a bit heavier, and exact
memory usage will vary with the particular sound card you have.
If you are using the ALSA drivers, then you might want to load the OSS
compatability layer. If you are using GNOME or have esd installed, you
might want to use xmms's esd output plugin.

The drive activity just started a few minutes ago, so I ran 'top' . The
only process that was using any significant CPU time was 'sort' being run
by 'root'. That must be the culprit.
Well now I learned something new, thanks.

See the wait(2) manpage. It is referenced in the manpage for fork(2). wait
will
get you the exit status of the process. It will wait until the process exits,
so if you
don't want the parent to wait forever, pass wait the WNOHANG option, or set
an alarm to wake you up out of the wait call using the alarm() system call.
