[Avila] GW2348-4 howto extend ramdisk size to 16M? (snapgear)

[gw at lunstad.com]

We switched to a 16M boot/RAM disk. We did the below, but wrt (3) we had
to upgrade our genext2fs. With that we also needed to modify the makefile
to specify a 16M fs and change the dev.txt file to support the new format
expected by the new genext2fs. I could post (or privately email) the newly
formatted dev.txt file (there are actually 2, one for 2.4 and one for 2.6
kernels, but we use 2.6 so I don't have a 2.4 version) if it would help.
It also contains patches to avoid security violations with the creation of
the device fs. This would have to wait til tomorrow, though, as I am out
of the office today.

hth,

Andrew
