I grabbed a Puredyne live dvd and it's the sort of thing I'd like to have installed as a boot option, but not live in. Unfortunately, it's not quite built like that.

The live dvd tells me (during a boot)
Not expanding HOME partition
Not expanding ROOT partition

and I get a number of silly things I need to tidy on this box, users, firmware, configuration. I have loads of ram and hd space available, and don't need it living in a postbox. To try and get the picture, I expanded the squashfs, and the initrd but it's definitely a learning experience - strange directories, a scripts dir with 332k of scripts (!)

Where the <expletive deleted> did they hide /home, and /root?
How much of this cripting crap can I ignore?
Am I going about this the wrong way?
Presuming yes to the last question, what should I do?
