[arch-general] Why does virtualbox-host-dkms have a hard dependency on linux-headers?

[Eric Engestrom]

Hi,

It looks like a mistake (on lines 249 and 276 on the PKGBUILD) was
introduced in commit b79afc2b72b306753b75ec600e1757e77735abf9:
https://projects.archlinux.org/svntogit/community.git/commit/trunk/PKGBUILD?h=packages/virtualbox&id=b79afc2b72b306753b75ec600e1757e77735abf9

I've CC'ed Seblu on this mail, he'll probably fix it when he gets the
time :)

The whole change is a result of the discussion that happened here:
https://lists.archlinux.org/pipermail/arch-general/2016-March/040862.html
Basically, someone complained of a missing dep, and it was explained
that you could have an other kernel than the default one.

Regarding your log, it looks to me like you have both the default and
LTS kernels installed, but only have the source for the LTS, so you're
only building the module for LTS.

Cheers,
Eric
