Since Sergey has contributed sysvinit, should su be "welcomed" back to
the sh-utils package? I'm suggesting this because some rc scripts
(e.g., PostgreSQL's) need su to function properly.
I understand that su requires special Windows privileges in order to
successfully setuid(). Maybe patching su to abort with the following
error message:
su: Currently only supported when run under the LocalSystem account.
when not run under the LocalSystem account is sufficient to help
minimize the mailing list support burden?
Anyway with the attached (quick) patch to su, I was able to start up
PostgreSQL using the standard PostgreSQL rc script via init with it
ultimately running under a "postgres" account.

P.S. Note that the patch is a starting point -- not a finished product.
