[Fedora-livecd-list] Re: Virt-p2v live CD, comments and packaging

[Tim Wood <tim wood datawranglers com>]

As a not-quite-counter argument, I've found that if each change is small (e.g. three sed commands to tweak a config), a longer kickstart can make a lot of sense.  Beyond short stuff, I will agree completely with Jeremy.  RPMs are not too hard to pull off if you have a little patience on the first one.  Guru labs has a nice tutorial you can google (the examples are google-able, too ... they just arn't in the same place)

On embedding stuff in the kickstart, one suggestion.  Use some sort of really really obvious delimiter and extra white space between each chunk (see the example below).  I've got a kickstart that tweaks a bunch of odds & ends in %post and this approached has saved my sanity and made maintenance and improvement much easier.

I'm posting here to see if anyone has any comments about the way I did 
this live CD.  The kickstart script uses a rather complex %post section, 
which adds a few files to the filesystem, instead of building RPMs or 
modifying existing RPMs.

long run if you actually package up things into RPMs as opposed to just
concatenating piles of scripts.  I've already gotten pretty frustrated
with just the initscript we're using in the desktop case on a few
occasions.

  

I've also investigated how to attach stuff to the end of the ISO image, 
and the way I've come up with allows me to update an ISO with a new 
script quite easily, and much more quickly than waiting for 
livecd-creator to rerun.  This great (a) for rapid development and (b) 
to send new updates to users without forcing them to download another 
170 MB ISO.
    

Ewwww :)
