hadrian: Reduce Cabal verbosity
The comment claims that simpleUserHooks
decrease verbosity, and it
does, but only for the postConf
phase. The other phases are too
verbose with -V
.
At the moment > 5000 lines of the build log are devoted to output from
cabal copy
.
So I take the simple approach and just decrease the verbosity level again.
If the output of postConf
is essential then it would be better to
implement our own UserHooks
which doesn't decrease the verbosity for
postConf
.
