This announcement arrived just a few minutes ago to the openSUSE mailing list:
I'm happy to announce the availability of SUSE Linux 10.1 "remastered".
This release combines the 10.1 GM and all online updates that we have
released for 10.1 so far, including libzypp, which should make the
installing and working experience much smoother for everyone.
We have created new CD ISO images and supplied delta ISOs from the
goldmaster. The non-OSS DVD images will show up next week, we had to
retract and will remaster. The ftp installation tree remains
The files have a "Remastered" in their name and a symbolic link from
the old name to them so that references will continue to work.
If you are running SUSE Linux 10.1 already, there is no need to
download these images at all. Just do an update from our update
repository to get all our security updates. This remastered media are
usefull for new installations.
I did not try it (yet), but it should work as described in my install guide available at: http://en.opensuse.org/PegasosQuickStart
And let me repeat what is already in the announcement: you don't need it if you already have 10.1 installed, only for new installs. But for new installs, it's strongly recommended!
