Package: kernel-package
Version: 10.011
Severity: minor

Installing a linux-image built on sid with kernel-package 10.011 fails
on a sarge system using lilo. It looks like the postinst script
doesn't properly handle lilo's zero return code. I have added debug
output to the postinst:

if (-T "/etc/$loader.conf") {
  # Trust and use the existing lilo.conf.
  print "You already have a $Loader configuration in /etc/$loader.conf\n";
  warn "use lilo.conf\n";
  my $ret = &run_lilo();
  warn "ret $ret\n";
  exit $ret;
  warn "after exit\n";
}

and here is the output of that script

$ DEBUG=yes sudo /var/lib/dpkg/info/linux-image-2.6.14.3-zgsrv.postinst configure
vmlinuz(/boot/vmlinuz-2.6.14.3-zgsrv) points to /boot/vmlinuz-2.6.14.3-zgsrv (/boot/vmlinuz-2.6.14.3-zgsrv) -- doing nothing at /var/lib/dpkg/info/linux-image-2.6.14.3-zgsrv.postinst line 580, <STDIN> line 2.
use lilo.conf
ret 0
$ echo $?
128
$ less

This, of course, makes aptitude barf.

What I find strange is, that an explicit "exit 0" right after the
"run_lilo" call makes the shell say "128", and an explicit "exit 0"
right before the "run_lilo" makes the shell say "0" as it should be.

This is very strange. Any ideas?

I inspected the changelog of current kernel_package and didn't find
any entries that indicate that this issue was fixed in more recent
versions of kernel-package.

Greetings
Marc

If I read this correctly, it is casued by update-grub writing to stdout,
This was fixed in 0.97-3. I will close this bug for now, please reopen
it, if you disagree.
