Regarding the -j option, I seem to remember someone telling me that
option was only for make buildworld/installworld and not the modules
or anything else. Anyone care to confirm and/or explain why? I see the
following in the man page:
The options are as follows:
<snip>
-B Try to be backwards compatible by executing a single
shell per
command and by executing the commands to make the sources
of a
dependency line in sequence. This is turned on by
default unless
-j is used.
-j max_jobs
Specify the maximum number of jobs that make may have
running at
any one time. Turns compatibility mode off, unless the B
flag is
also specified.
