Re: moving RedBoot config from one device to another - is "dd" enough?

If I do this on a "master" device (Linux already started):
# /dev/mtd3 is a "RedBoot config" partition
dd if=/dev/mtd3 of=new-redboot-config
And then, on the devices I want to reconfigure (Linux already started):
dd if=new-redboot-config of=/dev/mtd3
Will this work properly? Will the new device have its starting
sequence changed to:
RedBoot> fis load kern2
RedBoot> exec
?
Perhaps, I should use something like "erase /dev/mtd3 0 12 1" first?
The basic concept is O.K. Im not familiar with mtd, so i've no idea
if you need to erase the block first, or if writing to it will
automagically erase it.
I needed to erase it before writing the kernel, so perhaps it's similar
with RedBoot config.
Or maybe, there are some tools to manipulate the RedBoot config, without
actually starting RedBoot / using "fconfig"?
You should be able to telnet into the box to the RedBoot command line,
before Linux gets booted.
Manipulating the 'fconfig' database is tricky. There was some discussion
of this in the past on this list - try searching the archives.
