I must correct myself.

I should have written "Is there any part of installworld where
files/dirs/links are installed using tools other than ..."

Actually the total list seems really short to me;

[ awk cat chflags chmod chown date echo egrep find grep
ln make mkdir mtree mv pwd_mkdb rm sed sh sysctl
test true uname wc zic

I can think of three methods;

i)   a simple wrapper that attempts to parse the subset of
     invocations used by installworld, and maintain a log,
ii)  an LD_PRELOAD-based wrapper, taking advantage of recent
     dynamic linkage changes,
iii) building installation editions of those tools, so that they 
     maintain a log of activity.

Obviously not all are attractive.

Either way, the file exists.  I wasn't looking for anything more
sophisticated than that in a first pass at this.

Other than the general case of using install -C, can you
point out any specific examples?  I thought that was the point
of mergemaster; to manage elements of the distribution where
simply overwriting would be inappropriate.
