[Pkg-dkms-maint] Bug#830670: mkbmdeb lacks support for Provides:

[Craig Sanders]

Package: dkms
Version: 2.2.0.3-5

It's great to see that Bug#554843 is finally closed
and 'dkms mkbmdeb' builds a standalone binary package.  Thanks!

Unfortunately, this doesn't help anything that depends on the -dkms
package itself, or a -modules virtual package

For example, the 'zfs-zed', 'zfs-initramfs', 'zfs-dracut', and
'zfsutils-linux' packages all have:

    Depends: [...], zfs-modules | zfs-dkms, zfsutils-linux

The 'zfs-dkms' package has:

    Provides: zfs-modules

The 'zfs-dkms-bin' package built by 'dkms mkbmdeb -m zfs -v 0.6.5.7' has
only:

    Package: zfs-dkms-bin
    Version: 0.6.5.7
    Architecture: amd64
    Maintainer: Dynamic Kernel Modules Support Team <pkg-dkms-maint at lists.alioth.debian.org>
    Installed-Size: 3086
    Depends: linux-image-4.6.0-1-amd64
    Section: misc
    Priority: optional

This does not satisfy the dependencies of 'zfs-zed' or the others.

The binary module package should probably have a Provides: line
containing either or both of the 'Package:' and 'Provides:' fields of
the -dkms package it replaces.



BTW, The same is true for the 'virtualbox' package, which depends on
'virtualbox-dkms' or 'virtualbox-modules'. A quick check with

    apt-cache search -n -- -dkms | cut -d' ' -f1 | 
        xargs -n1 apt-cache rdepends | grep -v '^[R ]'

seems to indicate that this will be a problem with ALL -dkms packages.

PS: one current work-around is to use the 'equivs' package to build a
dummy package which has, for example:

    Depends: zfs-dkms-bin
    Provides: zfs-modules, zfs-dkms
