Description John Reiser 2010-09-24 00:02:57 EDT
Description of problem: An install DVD composed via pungi+lorax has an images/install.img that is 37MB larger than the same file composed via pungi+buildinstall.  The differences I found are (when restricted to shallow depth, more or less):

and after that I got tired.  There are also major differences in

Version-Release number of selected component (if applicable):
lorax tip as of 2010-08-12

How reproducible: every time

Steps to Reproduce:
1. compose install DVD of Fedora 14 Beta using pungi+lorax versus pungi+buildinstall
Actual results:
# ls -l /mnt/beta/images/install.img /mnt/lorax/images/install.img
  -rw-r--r--. 1 root root   157347840 Sep 20 21:44 /mnt/beta/images/install.img
  -rw-r--r--. 1 root root   194723840 Sep 23 17:16 /mnt/lorax/images/install.img
which is a 24% increase for lorax.

Expected results: At most a few percent increase in size.

Comment 1 Chris Lumens 2010-09-24 11:24:24 EDT
lorax inverts our current logic by blacklisting things instead of whitelisting things.  This is due to our years of experience at getting burned by not including required things no one told us about, files changing names or locations, and the like.  It's more worth focusing on what large things we can block entirely than on what the specific file-by-file differences are.
Comment 2 Martin Gracik 2011-03-14 04:45:00 EDT
We use a blacklist when creating images. So there may be some unnecessary files left in the images, but they are mostly small, and do not increase the image size so much, as opposed to us having to maintain a very long list of files to remove from the install tree.
