fai-mirror and conflicting packages

[Andreas Heinlein]

Hello,

does anyone know of a faster way to get conflicting packages in a
partial mirror created with fai-mirror, than using MAXPACKAGES=1?

I need to include both 'grub-pc' and 'grub-efi-amd64' in the mirror.
Downloading everything with MAXPACKAGES=10000 downloads ca. 1500
packages in one swoop in about 20 minutes, but leaves out grub-efi-amd64
because of the conflict. Downloading with MAXPACKAGES=1 should allow
this, but takes ages (I stopped after 4 hours).

Thanks,
Andreas
