Rainer M. Canavan reporetd that the Cobalt 2.6.31 snapshot doesn't
install. In fact, all kernels that do not use an initramfs are
currently uninstallable. Looking at SVN logs, I see that maks removed
various initrd handling because he thought it wasn't necessary. mips,
mipsel and some other kernels (e.g. s390) don't use an initramfs, so
this code is definitely still required.
I came up with the following patch reverting some of maks removals.
The package installs now but I still get the following warning:
Could not find . at /var/lib/dpkg/tmp.ci/preinst line 165, <STDIN> line 9.
Since I'm not very familiar with the config scripts, I wanted to ask
if someone else can take a look at this.
Here is the patch that sort-of works:
