uncompressed size

[Skunk Worx]

I'm using F9 and the livecd-tools-017.1-1.fc9.i386.rpm (from koji).

When I try to build my iso from a config, I get a list of rpm names and 
sizes, then livecd-creator bails out.

My set of rpms is large and apparently exceeds the 4096L * 1024 * 1024 
default value set in imgcreate.py. I found this by removing some 
packages and seeing a successful completion.

The older version of livecd-creator, used in F7, allowed me to alter the 
uncompressed-size via a command line argument. As a test, I added 512 to 
  the 4096L and it seems to create the iso successfully with all desired 
packages.

Does anyone have an opinion of how "dangerous" it is to change the 
default uncompressed size this way? I don't want to continue down this 
path if what I'm doing is considered grossly wrong.

Thanks,
John

Actually I'm pretty sure these days it's far more harmless.  The 
difference being that squashfs now supports sparse files more 
efficiently.  Really I'm thinking more to my obscure case of wanting 
both that(ext3fs size) customizable* as well as the virtual disk size 
customizable.  What the latter gets you is the ability to resize2fs 
upward online post boot (useful for very non-typical usage).

(*) jkatz- I'm too busy/lazy to look at the code, but is the size now 
customizable via the intuitive kickstart directives?  (e.g. size for / 
partition)

You can bump the size with something like
  part / --size 6000
in your config. See, for example, the games config
