Hi,

I was able to get HEAD running by setting the bootstrap ‘binary’ to 7.8
which I had build already using the nix package. I think that 7.6.3
would work as well but I haven't checked the Hydra build log yet. In any
case, this means that I have not pursued the issue further than what I
noted on my e-mails to the list.

My cycles on this are rather limited, I don't particularly care how I
get HEAD (or in this case the 7.8.3 branch) as long as I get it but if
you're able to provide 7.8.2-binary.nix (7.8.3 when released) then that
would certainly help in the future. If anything, it would cut down the
time required if you don't have 7.8.2 built already and ease the
situation when 7.10 rolls around in distant future.
