And it's not a bug report!

/me falls out of chair

I took a quick look at this, and it looks like the library (addline, delline, 
and friends) might work well with (or maybe as a replacement to) my dynamic 
UML reconfiguration scheme (see http://user-mode-linux.sourceforge.net/config.h
tml).

Basically, that involves creating a skeleton filesystem outside UML which 
contains the files you want to change.  You tar it up, and pass it in on the 
UML command line as ubd?=config.tar.  An early rc script inside UML looks for 
an environment variable pointing at that ubd device and untars the config 
files from it.

This happens early enough that you have almost complete control over the 
configuration.  You can't change the root device, but you can fiddle 
everything else.

As for the RPM stuff itself, you should base this on my latest mkrootfs.  I 
basically rewrote it a month or so ago.  Aside from that minor quibble, this 
looks very useful.

On a related note, if you can get hold of the RH 7.0 iso images and make a 
filesystem from it, that would be very cool.  I haven't been able to stay 
connected to a mirror long enough to grab the images.
