Bug#286578: coexisting d-i
Regarding the coexisting of different archs and versions in the netboot
tarballs (#286578), I just discovered the existence of the
di-netboot-assistant package. Among other things it appears to work
around the problem of netboot tarballs not existing by creating it's
own top level hierarchy.
I think this bug should still be fixed in the netboot tarballs produced
by d-i. Once it is then di-netboot-assistant (and any other netboot
management code/wetware working around this problem) can be simplified.
I was shocked to see this bug recently celebrated it's 6th anniversary!
