Default Desktop Live DVD: diff

Hi,

There has been some discussions about the increasing space constrains on
the Live CD and how we are better off targeting 1 GB USB keys with a
Live DVD image. I looked into it today and I have generated a image
based on the latest Rawhide.

The image size is 1022 M. Let me know if the following looks alright:

Fair enough. Here you go:

$ diff -u fedora-livecd-desktop.ks fedora-livedvd-desktop.ks

Default Desktop Live DVD: diff

There is at least one change I agree with: including OpenOffice instead
of abiword. The rest, I am not so sure about.

This is likely too big, remember drive manufacturers don't really use
units like KiB MiB or GiB - they use 1K = 1000, 1M = 1,000,000 and 1G =
1,000,000,000 - e.g. the SI units.

It seems to me that most 1GB USB keys have a size of 1GB = 1,000M =
1,000,000,000 bytes. Some are 1024MB (1024,000,000,000 bytes), some may
be a bit smaller (e.g. "value-adds" like the Sandisk U3 "CD-ROM") while
some may actually be 1024 MiB (1,099,511,627,776 bytes). It varies.

It would probably be helpful to do a quick study of actual sizes of 1GB
USB sticks - we may end up wanting to do a 990 MB (990,000,000,000
bytes) image or something so the image works on as many USB sticks as
possible.

Moreover, the closer you get to the full size, the less space you'll
have for any overlay.

Good point. A quick search on the Internet suggests that 2GB sticks can
be had for < $10. So maybe we should just bite the bullet and target 2GB
keys and do a 1.7GB (1,700,000,000 bytes) image leaving ~300MB free for
the overlay.

Then leaves both wiggle-room and also enables us to include *compelling*
stuff like Ogg Theora videos featuring Shadowman etc etc.

Personally I think one of the nice things about a live CD image is it
creates a good restriction for building a nice focused working system in
a reasonable amount of space. 1GB would more or less keep that; 2GB is
starting to introduce an awful lot of wiggle room for not caring about
including useless crap.

And remember, large USB keys may be cheap as chips nowadays but
bandwidth ain't, always. Aren't there still people in Australia with
absurd caps like 10GB/month?

I'm not sure I like the idea, if the idea is 'stop doing a small
functional live image and make our smallest 'complete-out-of-the-box'
image 2GB big'.

The biggest gap in terms of 'complete-out-of-the-box' is OpenOffice.
Including that brings us up to around 850M or so.

Finally we can move away from the 1990s (CDs), but yeah I agree
besides OO.org I can't think of an app that I really miss on the live
media.

Just because we do have more space available does not mean that we
have to fill it with random crap.
