How would I do that?
I never used grub before, so when I'm blind I have no idea how to do
such things. You did get that the screen is actually black when the
menu is supposed to be on screen? I can change menu entries blindly tho.
Walkthrough?

MacOs 10. something is what the customer told me.
I have just about zero chance of getting them to do a tcpdump for me.

Well, while https was enabled, there were no actual content there. What
seemed to be there is a phpinfo() script by default? It's running with
default ssl.conf and no files have been added to the dir.
We have renamed ssl.conf to make sure it is disabled now in hope that it
will solve this problem. This might have something to do with crackers,
as we are seeing some moderate hostility against just that server.

Fedora Startup Problems
by Ivan Gyurdiev
Hi, sorry to spam the list with bug reports.
I usually stick to bugzilla, but when my system becomes unusable
this is not cool at all, and I think deserves attention.
=====================================================
I rebooted to start up the 517 kernel. Initrd loads, the xfs module
loads, and I get "xfs error 6", after which the kernel panics
since it can't start init. (BUG 1)
So I reboot under 515, but the initscripts
hang on IIIMF forever (BUG 2) I don't understand why the initscripts
would hang on any service - is it not possible to time those and kill
them if they create problems? I've had to deal with this before.
I decide to reboot in single mode - 515 kernel...
I add single to the grub kernel line, and to my surprise the kernel
panics since it cannot start init. Removing single from the command line
fixes the problem. (BUG 3)
So I finally have to do an interactive boot on an older kernel
without single mode to get my system to work.
Can some of those bugs please be fixed?
I can test whatever is necessary.

The problem is that the label has a max length (filesystem dependent,
it's 15 chars for ext[23] iirc). So appending the UUID isn't really
doable.
Switching to mount by UUID instead of by label has been proposed a few
times, but I find it to be a fairly disgusting thing to have to expose
at all and thus have resisted the suggestion.

I suppose using the UUID alone in /etc/fstab would be unnecessarily
obtuse. I work in a laboratory environment that does digital media
forensics, sometimes on evidence in criminal cases. Therefore we need to
be absolutely certain we aren't writing to any partitions that don't
"belong" to us.
I always reconfigure /etc/fstab on my workstation, after installation,
to reference UUID= instead of LABEL= for all my system partitions. The
only problem with that approach is that I can't simply do the same thing
in GRUB. Appending the UUID to the LABEL would take care of the problem
without having to make more than a trivial change; is this something to
propose for anaconda perhaps?

It's nice but only as an aid to a packager, it has too many problems to be
usable in automated manner. For example try it on the little script
below... Dunno how hard it would be to fix.

#!/bin/sh
dostuff()
{
echo "stuff..."
}
$grep="grep"
echo `ls`

Nice, I didn't know this was there. What would the implications of running
this as a per interpreter find-requires at build time on shell scripts?

We patch our bash package to have an --rpm-requires option to provide
just this functionality (but it isn't used).

This is a bug in the old bison package and it should have been re-issued as an
update IMHO. Under no case should m4 be added to a buildrequires unless that
package actually uses m4. Otherwise you muddy the real requirements for a
package.
>> Your buildsystem should always require m4 until our source base is cleaned

I disagree with this. Very few packages actually use m4. Because you have people
that need bugs fixed when no updates are provided, its pretty common for people
running an old RH system to get the latest package and build it on their system.
Therefore, the baseline has to be enforced by rpmbuild. m4 is not required by
rpmbuild.
Another thing, you have to be careful not to add too many programs to the
baseline development requirements. Otherwise you lose the tracability of what
contributes to each package. Suppose one day that a bad version of m4 was
released and m4 was a common requirement. You would not be able to trace all the
packages that might be affected.
>I've applied a few buildreq fixes from Steve Grubb, hopefully I'll get his
>next set soon and can carry on merging them.
Yes, next batch is being sent. I have the full & exact buildrequires for about
220 packages. My buildsystem borrows some ideas from LFS. It can bootstrap build
a distribution from a host system like a stripped RH9. When I started this
project back in March, my buildsystem showed FC only needed 6 passes to get all
the packages build. There were many missing dependencies and circular
dependencies. It did not build to completion. I started correcting everything.
Now, my buildsystem shows 19 passes to get all packages built. It consistently
builds now.
You can look at the build dependency diagram (not the runtime dependencies) from
here: http://www.web-insights.net/dep.ps.gz I recommend KGhostview, but any ps
viewer should do. Simple packages are at the top, packages that depend on many
prerequisites are at the bottom.
Speaking of runtime dependencies. I was researching a security related bug the
other day and ran across a neat feature of bash. --rpm-requires will print out
the external programs called by a sh script. I started comparing the runtime
requirements of shell scripts versus what is stated.
For example, /sbin/grub-install. The grub package states bash & texinfo. I get
coreutils, diffutils, grep, and sed just for that one file! It would be nice if
rpmbuild scanned for shell scripts, capture the info, resolve the files to a
package, and add the packages to the runtime requirements. Its really simple.
http://www.web-insights.net/sh2rpms if you want the bash script.

The problem with no BIOS HID emulation being bootloader control. Or do
the latest Lilo/Grub incarnations understand HID input ?

The problem with this one is that order is meaningful. How do you
decide which one comes first with a random collection of files? I
suppose you could use a system of symlinks or something (but then GRUB
can't live on a non-Unix FS), but it is getting complicated for
something that (hopefully) doesn't change much.
