Public bug reported:
Filing this against the 340-updates version but possibly the same
applies to older versions, too. The nvidia source package produces three
individual dkms packages: nvidia-340-updates, nvidia-340-updates-uvm,
and bbswitch-dkms. The problem is that the DKMS build of the nvidia-uvm
module runs compile steps inside the nvidia modules build directory.
This is violating the DKMS assumption that each module can be build
independently (there is no way of describing cross-modules dependencies
and even more important, the autoinstall step after a new kernel is
installed will run the modules build in parallel).
Since nvidia and nvidia-uvm are very dependent on each other the right
course of action seems to be to combine both sources in one DKMS module
that produces two kernel modules (this is supported by DKMS). For the
transition this resulting dkms package needs to have a breaks/replaces
for the nvidia-uvm package.
