On and off I've been looking into the differences between how
debian-live and normal Debian call ipconfig from the initramfs. I
see that in scripts/live there is:
585 if [ -z "${NETBOOT}" ] && [ -z "${FETCH}" ] && \
586 [ -z "${HTTPFS}" ] && [ -z "${FTPFS}" ]
587 then
[…]
632 else
633 ipconfig ${DEVICE} | tee /netboot.config
634 fi
Without timeout (-t) on the ipconfig line it does wait forever to
get all info from DHCP.
In a normal Debian initramfs it
(/usr/share/initramfs-tools/scripts/functions) looks more like this:
http://paste.debian.net/161968/
$IP here is coming from the kernel command line ip= option, so I
tried same with scripts/live:
633 ipconfig -t ${ETHDEV_TIMEOUT} ${DEVICE} ip=${STATICIP} | tee
/netboot.config
This then does allow me to netboot a debian-live install without
having to have it configure via DHCP+TFTP.
I don't really know what I'm doing so I don't even know if you
consider the current behaviour a bug. Is it worth filing this as
wishlist bug?
Cheers,
Andy
