patch: flashdist - openbsd3.9

Manuel Pata
Ora aqui vai um pequeno patch para o flashdist que remove os debug
symbols das libraries do openbsd 3.9 de forma a caber tudo num
CompactFlash de 32mb. (para desactivar esta nova funcionalidade correr o
flashdist com o argumento -g no final)

Este patch também impede o Soekris de ficar parado eternamente no
bootloader à espera de uma intervenção do utilizador.

Testem e digam qualquer coisa ;)
<http://alface.de/untitled/flashdist.sh.diff>


Dica para não estarem sempre a escrever no CF:
dd if=/dev/zero of=soekris.img bs=1k count=3200
vndconfig svndX soekris.img
<http://www.openbsd.org/faq/faq14.html#MountImage>



"Flashdist is an embedded OpenBSD installer. It will install OpenBSD
onto an attached disk, such as an IDE or USB CompactFlash adapter,
Disk-On-Module, hard disk, or whatever. It is designed to install a
minimal version of OpenBSD with features for networking"
