Debian switches off caching of the hosts database in nscd for instance (since
glibc 2.5), that's why it works there. I guess Redhat either does the same, or
these old glibcs really behaved differently. I can't see how how current libcs
would ever have worked differently. With nscd hosts caching the
__libc_res_nquery routine never is entered (and never was), and that's the only
one that calls res_hostalias, and that's the only one that respects this
environment variable.
It's either a documentation bug or a code bug, but in any case it's an upstream
bug, now reported here: http://sourceware.org/bugzilla/show_bug.cgi?id=13375
