Ok, now after a collegue of mine informed me about the existence of
tsort (*blush*), I could finally produce some more info about loops
in our dependencies. I wrote a simple script:
awk '/^@ /{ left=$2; }
/^requires: /{ for (i=2; i<=NF; ++i) print left " " $i; }
' < setup.ini | tsort
It found the following dependency loops which have to be fixed.
Most notably are the dep loops of _autorebase and _update-info-dir,
which we'll fix ASAP.
