I setup a local mirror of the Fedora 16 development repo and got to work on the MontanaLinux LiveDVD remix. I ran into a few minor problems but the 32-bit build seems to be working great now.
Now that grub2 is used by default and grub is also in the repos, you actually have to add grup2 to your package list in the kickstart file or it isn't there when you try to do an install. Check.
When using the sample KDE kickstarts to add to, make sure and remove a few of the really big packages you don't want or your iso may grow over 2 GB at which point a few of the later build pieces may get cranky. After removing a lot of koffice translations, octave, and a few other things... my iso went from 2.1 GB to a more desirable 1.8 GB. Check.
Packages that I noticed that disappeared in Fedora 16 that I needed to remove from the package list: agave and xfprint. Check.
Since grub2 is used the process of rebranding grub has changed and I haven't figured that out yet. In fact, I still need to learn how to customize grub2 since it is no where near as obvious as the grub.conf used to be for grub1.
New stuff in Fedora 16 I still need to figure out
Anyone got grub2 all figured out yet? From what I understand there are a number of config files, and then a few for settings... and then some process to build from those the config file. Editing the config file directly is a no-no.
systemd is now in full force and legacy tools like chkconfig and ntsysv still work but to a lesser degree. The legacy tools only show a subset of services rather than all of them and I haven't figured out yet how to get a complete list of enabled services from systemd.
chkconfig httpd on" has become "
systemctl enable httpd.service". I'm just not sure what the systemd equivalent for "
chkconfig --list" is yet.
I still have to work on the 64-bit version but now that I have a functional 32-bit kickstart, that should be a piece of cake. I should have everything done before or by the official Fedora 16 release date which currently is set for 2011-11-08.
I got tired of having to delete about 100 bogus comments from anonymous users every day. Anonymous comments were moderated so none of the spammy ones would get posted so it was a total waste of time to post them in the first place... but bots don't seem to learn.
In any event, I hate having to sign up for an account just to leave a comment on a site... so an alternative is to just email me your anonymous comments along with the URL that they refer to - email@example.com. I'll give it a week and see how it turns out. I am NOT a fan of captcha so I don't want to burden all users with that either.
Site registrations have been turned back ON but registration requirements will be enforced.
For our Ubuntu fans as well as those who just want to learn about the upcoming release, I found this on youtube. I was hoping for HTML5 playback option, but this seems to be Flash only. The review was done from a recent release candidate that I believe will be the final release due out this Thursday. I still prefer KDE myself. :)
I'm not much of a fan of Jim Kramer... but here's the video.
Flash is the best I could do. Sorry for the small size and internal branding/ads.
The KVM Forum 2011 was held at the Hyatt Regency in Vancouver, Canada on August 15-16. It was co-located with LinuxCon North America 2011.
LinuxCon and the KVM Forum were both sponsored by The Linux Foundation who recorded a large number of videos from both events. Unfortunately, The Linux Foundation had few security breaches to deal with on their kernel.org and linux.com domains which (I'm guessing) has greatly delayed them doing post-production work on the recordings and posting them publicly.
I found that Red Hat had recently posted a handful of the KVM Forum videos to YouTube but since they were only available in the flv and mp4 formats, I decided to re-encode them and post them to archive.org as webm (a free, open source, non-patent encumbered video format). I think archive.org is really a better place for them. Red Hat released them under a Creative Commons, Attribution - No Derivative Works 3.0 License. I have not altered the videos in any way other than re-encoding them to webm in a smaller resolution (624x352) and bitrate (664Kbit) making them one half to one third of the original filesize yet maintaining reasonable quality. Modern Firefox, Google Chrome, and Opera browsers can play webm as can stand-alone players like VLC, Totem, and mplayer.
They are all highly technical presentations for those interested in the nitty-gritty details of the Linux KVM virtualization Hypervisor. I have embedded the first, short keynote video below and given download URLs for the rest. Thanks to Red Hat for posting them!
One thing to note is that the camera / recording is statically positioned and does not show the presenter slides so I have also included the links to the slide decks in PDF format. For a better understanding, you are strongly encouraged to look at the slides while watching the videos. Also be warned that some presenters may occasionally use curse words.
Here's a zip file containing all slide decks in PDF format for all of the presentations.

Red Hat produced a video entitled Default to Open: The History of Open Source and Red Hat. Since it is about history, it has a number of older clips... bits and pieces I've seen before but quite a bit of new stuff too. Enjoy it embedded in webm format or use the link below to download it for local playback.

This is the second Sansa product I have bought. The first one was the Clip that served me well for a few years until it died. In need of a new device I saw the refreshed product line from SanDisk that includes the Fuze+, the Clip+ and Clip Zip. For hardware I'm usually a very late adopter. For software, being a Fedora user, not so much.
I tend to buy stuff for myself from the discount computer sellers online like newegg.com, tigerdirect.com and geeks.com. I had a $25 credit from geeks.com so I decided to check out what they had and found a refurbished black 4GB Fuze model for $28.88. They also had a Fuze+ model but it was about twice that... so I opted for the Fuze.
The Linux Foundation has put together a 20th Anniversary of Linux Gallery with a timeline and a lot of donated items from various companies and members of the Linux community. As luck would have it, I ripped this from youtube so I could repost it in webm format and noticed that in the original the metadata for the audio stream said -
creation_time : 1970-01-01 00:00:00. While that isn't quite true for Linux, which was started in 1991, it is basically the Epoch time considered to be the start of the UNIX universe. :)

Greg and Linus sat down for an open discussion about Linux and its 20th anniversary. They even take questions from the audience. This is from the LinuxCon Japan 2011 held in early June. They had a very similar discussion in August at LinuxCon North America but the video for that hasn't been released yet. Having seen both, I think this first one actually covers more stuff. Unfortunately the introducer takes a few minutes before we get to see Linus and Greg. In webm format.

Jon Corbet did another of his Linux Kernel talks at the LinuxCon Japan 2011 in early June. This is his Linux 20th Anniversary edition where he goes into a lot of the history of Linux so this talk is a bit different than his previous ones. Here it is in webm format.
