Ignore the last comment. Cannot run test from command line.
What I did find is that the postinstalls succeed when I run them from a
Cygwin shell as Administrator:
bash-4.1$ bash.exe -norc -noprofile /etc/postinstall/coreutils.sh
bash-4.1$ echo $?
0
bash-4.1$ bash.exe --norc --noprofile /etc/postinstall/bash.sh
bash-4.1$ echo $?
0
So why the exit code of 128 when setup runs these postinstalls?

Gerry
