Missing documentation about vmlinux / linux-image-debug.ddeb

[Steffen Neumann]

Binary package hint: oprofile

Hi,

The README.Debian.gz has some information about how to build
a working vmlinux: make-kpkg with install_vmlinux=YES in /etc/kernel-pkg.conf.

The #ubuntu-kernel team strongly discurages that:

  [14:16] <smb> sneumann, nooooo, please not make-kpkg
  [14:16] <smb> sneumann, There is no warranty this ever has (for a while) or will work

and pointed me to the linux-image-debug-2.6.31-*.ddeb
available from http://ddebs.ubuntu.com/pool/main/l/linux/

I guess that should be added to the documentation of oprofile.
The bug #/289087 gives some background and links.

Yours,
Steffen

Sorry, got the wrong URL: ddeb.archive.u.c is not in sync.
Current ddebs are available from
