[nycbug-talk] tracking for multiple machines

[Bjorn Nelson]

NYCBuggers,

I ended up making a shell script (see below) that puts a lock file  
in /usr/src before starting a build.  Then I made a BSDmakefile that  
includes the Makefile as long as the lock file isn't there or you set  
the BUILDOVERRIDE variable.  make grabs BSDmakefile or makefile  
before Makefile:

< snip to line 789 from /usr/src/usr.bin/make.c >
         } else if (!ReadMakefile("BSDmakefile", NULL))
             if (!ReadMakefile("makefile", NULL))
                 (void)ReadMakefile("Makefile", NULL);

So as long this doesn't change, this method should be okay.  Let me  
know if you see any land-mines.

Thanks,
Bjorn Nelson
