[Nix-dev] Hydra failure types and Nix support

[Michael Raskin]

16596922		mda_lv2.i686-linux	
16591197		mongodb.x86_64-linux	
16599836		qbittorrent.i686-linux	
16599870		qbittorrent.x86_64-linux	
16590792		syslogng_incubator.i686-linux	
16604362		syslogng_incubator.x86_64-linux	

Of these I think that all failures except mongo are transient, and mongo
has just declared that 10GiB /tmp/ is too small — rebuilding with 
a larger /tmp/ to check.

1. Hydra seems to merge «new failures» and «still failing» in the same
tab. It may be what we want, but is it intended to call the tab «still 
failing»?

2. Apparently real failures end with «builder failed with code …».
Should the failures without that line be marked in a different way?

And yes, mda_lv2, qbittorrent and syslogng_incubator can be restarted…
