Is Ubuntu now supported?

[Steven Grunza]

I just noticed
ftp://ftp.rtems.org/pub/rtems/linux/4.11/ubuntu/dists/natty/rtems4.11/
on the RTEMS site.  Is Ubuntu going to be supported going forward or is
this a one-time deal? 

The Wiki page at http://www.rtems.com/wiki/index.php/APT/Yum_Repository
mentions the rtems-BRANCH-apt-conf-VERSION-DISTRIBUTION.noarch.rpm which
doesn't seem to exist.

The Wiki page at  http://www.rtems.com/wiki/index.php/Debian_and_Ubuntu
mentions using the alien package to convert the RedHat .rpm files into
debian packages.

Seems like there are now (sort of) three ways to get RTEMS packages into
a Ubuntu system.  I've Google'd around looking for details about RTEMS
on Ubuntu; if I missed something please point me to it.
