Run yum update on liveBLAG-79999.00032.iso and the process will go and get the latest data. However the system appears to be unresponsive once complete. Performed as a paravirtualised Xen image. Has anyone updated a running alpha live iso and if so what was the outcome?

You mean running `yum update` while the liveCD is running or of an installation based off a liveCD? I've done it on 79k installations a lot (well, mostly with apt)

Yes, whilst the live cd is running. Is one supposed to do that or not? Everything else works fine thus far.

Well, ya you can do it, but it's a bit of a waste since the update is lost.

OK. That is fair enough. There is no point in updating a live cd but I've always been curious to know the out come. It was a virtualised "machine" so it was safe to thrash it. By the way, within the live cd, df tells me that there is a total of 4gb! is wonderment this a result of the squashfs?

Actually, I may be wrong on this. If you do a `yum update` after booting the live CD and install with `liveinst` (you currently have to edit the anaconda line in `liveinst` and add --noselinux) then the system that gets written to the hard drive should be the updated system. I'm not sure what the merits are to doing it this way.

Though of that 4gb not all of the space is used--a lot of it is empty.

Which brings me to something interesting I came across.

What it is is that ext3 doesn't actually go through and zero out those sectors so they still have data that gets compressed in the squashfs.

I've yet to use this tool to make a live USB key fob. Following on from what you've said it would be interesting to install say, 80k on a stick and run df within that. If df showed more than the physical size of the key fob that would be crazy.
