illumos gate

Illumos contains private fork of wu-ftpd as its ftpd server. wu-ftpd upstream is dead for 10 years and wu-ftpd was considered as one of the most unsecure Internet daemons. There are much better replacements these days, like proftpd (Solaris 11 delivers it as the default ftpd), pure-ftpd, vsftpd and even original BSD ftpd is currently in better shape.

wu-ftpd should be removed from Illumos and distros should decide which ftpd they prefer.
