Yes, and the 'elaborateness' is controlled by the -v setting.
The point is that "Can't find unit foo" can have several causes.
To find out the exact cause, you must use -vu. To find out even
more, you use -vut. after that, it's -va...
RTFM is not an excuse, but people should also take some initiative
and start looking for the cause of trouble. The first thing is to
increase the verboseness of the compiler... For this, you should
read the manual.
It's hard to determine the exact number/amount of messages that is
useful to detect/resolve problems. To get more 'feeling' for how
to resolve problems, one can and should read the manual...
