Package: base-files
Version: 10.3+devuan3.1
Severity: serious
Justification: Can cause the build of other packages to fail and may
cause problems for programs checking if a system is a debian based system.

The file `/etc/dpkg/origins/devuan` should contain the following line
Parent: Debian

Without that, `dpkg-vendor --query Parent` won't output anything, it
should return `Debian`.
This is needed for `dpkg-vendor --derives-from Debian` to return true
instead of false.
There are tools which use this to check if a distribution is based on
A particularly problematic example of such a program is
`dpkg-buildflags`, which is used when building any package which uses
As it is now, `dpkg-buildflags` won't set any flags, which can break
package builds.
By adding `Parent: Debian` to `/etc/dpkg/origins/devuan`,
`dpkg-buildflags` would add the same flags debian uses.

However, before adding this, it has to be made sure all devuan specific
packages will still build with this change (btw. the default debian
flags applied.)
