squashfs FAI config space via http

[Michael Tautschnig]

>         mksquashfs . /var/www/cspace/fai-cspace.img -all-root
>         (cd /var/www/cspace/ && md5sum fai-cspace.img > fai-cspace.img.md5)
>         chmod 644 /var/www/cspace/fai-cspace.img*

> My fai.conf variable is:
> FAI_CONFIG_SRC=http://172.16.42.7/cspace/fai-cspace.img

> A verified a successful installation on a Debian/squeeze host and

No feedback related to this specific patch as I wouldn't require such a feature
myself, but I'd really appreciate if you just committed that to SVN yourself :-)
I'd love to not be the only one to use this branch anymore!!

Best,
Michael
