Thank you!

As I was not aware of symbolics with umask yet, and being paranoid, I've
tried that: Unfortunately, it depends on the shell if umask with
symbolics works: It works with bash as well as AIX' /bin/ksh, while it
does not work with AIX' /bin/sh, but without any failure notice - it
just sets umask to 0:

$ /bin/sh
sh$ umask
0007
sh$ umask o-rwx; umask
0000
sh$ umask 007; umask
0007
sh$ umask junk; umask
0000
sh$ 

So we want to use the numeric umask here...

Thanks!
