From Apple's Tech Q&A Stack (Q 83):
Another possible problem is caused by a bug in some third-party INITs that
cause the MPW installer to fail. This bug is caused by those INITs using
PBHSetVol and changing the default volume behind MPW's back This problem is
frequently reported by users with TOPS (from TOPS, a Sun Microsystems
company).

Some INITs use PBHGetVol to get and save the working directory, then attempt
to restore it using PBHSetVol, but end up setting the working directory to the
root instead. Tech Note 140, "Why PBHSetVol is Dangerous," warns against using
PBHSetVol.
