Bug#263169: initrd-tools orphaned?

Herbert Xu wrote:

However, /proc/modules is fundamentally broken because it prevents
someone from installing an initrd kernel while running a kernel with the
driver built-in.

So what we need is a kernel interface listing all drivers in the
sequence they were initialized, their module filenames (even if
they are compiled in), the major and minor device numbers, and
their driver parameters. Did I miss something?

Sounds easy ;-).

You can't assume that they are all loaded by the initrd.  You must
consider users with the drivers built-in as well users who load
modules after root has been mounted.  How else is someone going to
install an initrd kernel while running a non-initrd kernel?

But for this case it is impossible to provide the old driver
load sequence for the new initrd. You don't know what is
compiled into the new kernel, either.

The scsi modules found via /proc/modules are _appended_ to
the list of modules found so far. The sequence of modules
found before mkinitrd looked into /proc/modules is not changed.
It doesn't get worse, AFAICS. ALATBSOL.

This is broken.  For example, on a machine that boots of SATA while
also having another SCSI card with a disk attached, doing this will
cause the non-SATA SCSI disk to become /dev/sda.

I have appended the '|tac'. Attached you can find a new patch.
But I agree that the /proc/scsi problem should be investigated.
I have already asked the kernel developers about this problem
some time ago, but there was no response. Should I ask again?
