I'm sorry, I gave you attitude when I was frustrated. You didn't deserve
that.

I didn't edit grub.cfg, and this is not the first time I installed
grub-pc. I've been using grub-pc for a few months. The edits I did do
consisted of commenting out lines. I don't know the syntax, but I
understand enough to figure out what a conditional block looks like.

When the new version came out, I took a snapshot of the virtual machine
I was testing on and held my breath. The problem seems to be I can't
hold my breath long enough.

If I wait a bit longer I get a menu.  The menu is slow to the point of
unresponsive, but I get a working system if I wait for it to pick the
default.

At this point I assume all of grub2 executes at ring 0 and the slowdown
is due to virtualbox moving all of it to ring 1. I'll reinstall grub-pc
on my tower and see if it's fixed. If so, I hope I didn't waste too much
of your time. Despite my complaints, I like grub2 a lot and I'm really
impressed with the progress it's made.

Bug#466598: grub-pc chokes on grub.cfg, hangs before menu

2008-02-19 Thread Barry Schatz

Package: grub-pc
Version: 1.96+20080216-1
Severity: critical
Justification: breaks the whole system

Using the newest grub-pc package, I ran update-grub and then
grub-install. Chainloading doesn't work by the way, because
it doesn't create the chainload option in legacy grub. Booting
straight to grub2 results in "Welcome to Grub" and an
unresponsive computer.

In a previous release the if statements created by 00_header
PROVIDED BY THE GRUB-PC PACKAGE were a problem, but removing
those if statements doesn't avoid the problem any more.

I have had this problem on two computers, one a desktop and
one a virtual machine.

Bug#464464: grub-pc: syntax error in generated grub.cfg

2008-02-06 Thread Barry Schatz

Package: grub-pc
Version: 1.96+20080203-1
Severity: critical
Justification: breaks the whole system

The If-statement 00_header writes to grub.cfg is malformed, and causes grub2 
to get stuck in an infinite loop of syntax errors.

This code breaks the system:

  if font (hd0,5)/usr/share/grub/unicode.pff ; then
set gfxmode=1024x768
insmod gfxterm
insmod vbe
terminal gfxterm
  fi

My fixed grub.cfg is below. I fixed 00_header the same way:

  font (hd0,5)/usr/share/grub/unicode.pff
  set gfxmode=1024x768
  insmod gfxterm
  insmod vbe
  terminal gfxterm

Is there anything I can do to help you resolve this?

If this is a common problem, please change the zsnes dependencies to require 
libc6 < 2.5.

Thank you,

Barry Schatz
