Hi. I've got just a short question: Is creating of a live dvd possible with the current version of livecd-creator (001-3)? A few minutes ago I've tried to create one. The size of the packages to be downloaded was 1.0 Gb. Then yum fails with an transaction error. There was not enough free space on the filesystem. Sebastian

Hi.
I've got just a short question: Is creating of a live dvd possible with
the current version of livecd-creator (001-3)?
A few minutes ago I've tried to create one. The size of the packages to
be downloaded was 1.0 Gb. Then yum fails with an transaction error.
There should not be enough free space on the filesystem.

The big thing right now stopping it is the hard-coded 3 gig os.img.
Making it possible to specify that should be pretty straight-forward --
if someone wanted to take a crack at the patch, it would be good. My
personal preference would be to specify something like "part / --size
5000" or whatever in the kickstart config and if that's not specified,
we can fallback to something sensible much like we do now.
If no one gets to it first, I will eventually.

It's a sparse file backing the file system so just make it 100GB (or
2-32TB since ext3 supports that nowadays) and then resize2fs it down
before completion so it's approx 2-4GB larger than the payload in the
file. No need to add an option for this.

I seem to remember something which makes resizing less of a good idea
when you're shrinking. But my memory is fuzzy on what it is now.
You'll definitely take a hit on creation time if doing a significantly
larger filesystem like this, though, as mke2fs and resize2fs aren't the
fastest operations in the world.

That's true. Another reason it's useful if for livecd creators that
don't want to spend time compressing the image. So I added an option for
this along with other enhancements.
http://git.fedoraproject.org/?p=hosted/livecd;a=commit;h=df22a8438021ad76...
so now you can do things as shown in [1]. From a warm cache, the minimal
live cd now builds in around 2 minutes if you use --skip-compression and
local repositories. That's pretty nice.
