That's intimidating... If we had to ask linus for kernel
code or alan for network code, or becker for ethernet code,
where would we be? My point in asking the question is that
searching for information on this project, other than
this redhat employee is "working on it", has turned up little.
Saying that somebody is working on something, even though that
somebody has many other responsibilities, might cause someone
else not to work on a similar project. It's been this way for
quite a while, to the contrary of "release early, release often."
Of course you will probably tell me again, ask Stephen...

Okay. So all the solutions are tba at some unspecified future time,
if at all. We have several rock-solid kernels (I'm thinking DU, BSD, and
Linux), but we just don't have the good tuned filesystems yet. The
people who may or may not be working on such a thing are not giving
the community much to work with here. If Stephen has anything at all,
he should let the world in on it. If he has nothing, he should work
to dispel the myth that there will be anything like a jfs coming anything
like soon, and maybe more people will take an interest in something like
dtfs, which at least isn't vaporware.
Excuse me for ranting, but I think it was about this time last year,
same story, Tweedie is working on it...

it is. it's only a kernel and not a libc. there are few things you
will need to upgrade - modutils, binutils, dhcpcd, ipfwadm->ipchains
&c. check kernelnotes for the low down. there really are not all
that many things to fix.

I expect to have publicly testable code for journaling over ext2fs in
about 4 weeks or so.

good question :-)
But it was just an example, the program to handle telnet could be set to be
any program by editing netscapes preferences, so an xterm could be started up
on its own, or any other program that the users knows the path and has the
correct permissions for on the system.

You know, I think linuxconf hosed lilo.conf when I used it to add a
password to lilo (thought I'd see what all the hoopla over linuxconf
was about). I'll investigate further. Thanks for all the responses!

I'm using RH52/SuSE6.[0,1], and neither of these two fail like that..
In SuSE, the approach is to run fsck with "-A -a", which seems ok..
Also, SuSE 6.1 uses e2fsck-1.14, so I think these flags should be a safe
bet..
The "-F" is defined as:
-F Flush the filesystem device's buffer caches before
beginning. Only really useful for doing e2fsck
time trials.
The "-a" is said only for backwards compatibility, use "-p" instead..
The "-p" is defined as:
-p Automatically repair ("preen") the file system
without any questions.
and the "-A" is defined as:
-A Walk through the /etc/fstab file and try to check
all file systems in one run. This option is typi�
cally used from the /etc/rc system initalization
file, instead of multiple commands for checking a
single file system.
The root filesystem will be checked first unless
the -P option is specified (see below). After
that, filesystems will be checked in the order
specified by the fs_passno (the sixth) field in the
/etc/fstab file. If there are multiple filesystems
with the same pass number, e2fsck will attempt to
check them in parallel, although it will avoid run�
ning multiple filesystem checks on the same
Of course the root file system must be mounted in ro-mode to
successfully
be fsck'ed, but at boot, that should be the normal status..
Hope this helps.

tosi

The *essay* was about the development _process_, which IS an engineering
document. The *essay is about the cathedral vs. the bazaar development
models. Linux vs. Windows was just an example of these these processes.
Since I don't know how Windows does its development internally, i.e. it
could be using the bazaar style, I don't know if this example is valid.
This is the kind of weak argument that ESR provides. His entire paper
*seems* to be based only on opinions, but people are taking it as law.
>(and there are no absolutes, no matter who's doing the talking).
There's a problem here. ESR is pushing this view onto the entire software
industry. I think we must be more clear on the issues if we want the
software industry to end up on a better plane than it is now.

Does the spectator expect to change the way the software industry works?

First, in GNU/C++ the method -> #include <iostream> <-- is 'more
correct'
Second, use: c++ -o execfile sourcefile.cpp
( no errors, fine source file )
bash-2.02$ vi cpay.cpp
bash-2.02$ c++ -o cpay cpay.cpp
bash-2.02$ ./cpay
The pay is: 500

Let me get this straight; scientists, professors, graduate students, should
accept new theories at face value? This is the environment one should

Tests are the way to verify something, not find out about something. You
find out by doing calculations. Then you verify the calculations with tests.
This is the scientific process.

The definition of death is not the main point. The original question was:
'how can you prove people will die'. People die because their bodies
fail. The body fails because of cellular deterioration.
The only thing the above suggests is that the person was not deteriorating.
If his body was deteriorating, he would have no body to wake up to.
