I have built a modified version of initramfs-tools package that has as
default those Reiser4 -specific settings
but wanted to allow d-i to select most of its packages from regular
Debian repositories.

I will keep in mind your suggestion while I think about improving the
user experience, though. Thanks.

That suggestion is probably fine for the reiser4-parted DEBs but the
kernel included in d-i is 'picky' and I have not had luck changing its
name to something other than *official* Debian because d-i then
refuses to install from the Debian repositories.

Notwithstanding, one way that I have prevented overwriting
Reiser4-enabled Debian packages is by placing a *hold* on them, thus:

For the kernel, for instance:
echo "linux-image-4.3.0-1-amd64 hold" | dpkg --set-selections

And for Debian Parted:
echo "parted hold" | dpkg --set-selections
echo "libparted2 hold" | dpkg --set-selections

And we can check for those packages effectively being on *hold* and
not replaced by Debian package manager, thus:

dpkg --get-selections | grep linux-image
dpkg --get-selections | grep parted

After Debian is installed, a custom kernel version/name will survive
-- as well as an official kernel on *hold* ; however, during a *new*
Debian installation d-i seems *very* picky about matching
kernel/changelog version(s) with packages in repositories.
