Hi Mats,
I posted it before; unfortunately the archive doesn't save the attached
files.
Here is the original post: http://9fans.net/archive/2014/08/78.
Please see the attachment for the script.
Cheers,
Dante

Hi dante!
I would appreciate it a lot if you could send the "clone script" that
you used to clone the 9pi imate to a larger SD card. Thanks
beforehand!
Kind Regards,
Mats

If you must use a rpi, you should strive to use it as a terminal, and
like every other Plan 9 terminal it should use the central file
server
without local storage.
That would be my advice too. As an experiment, I set up a 9picpu
using
the SD card as local storage, working mostly as a secondary smtp and
imap
server. After a bit less than a year, the SD card suffered a
catastrophic
failure. When I say catastrophic, I mean I can't find any meaningful
data
anywhere in the first 120MB or so of /dev/sdM0/data ... just
not-quite-random
looking garbage.
I can't think of any software fault that could wipe out so much of a
disk, with no respect for partition boundaries (the dos partition in
the first 64MB had not been mounted). But I also know too little
about
the internals of SD cards to understand how they fail. Maybe some
internal logical-to-physical block mapping table went bad?
Anyway, it's just one anecdotal data point, but I wouldn't be happy
running any plan 9 machine with an SD card as the main filesystem.

# Use a USB adapter for SD cards in order to write another SD card.
# The storage device will be used at its full capacity, in contrast to the
downloadable image.
# Moreover, no additional computer is required for the installation.

# This program makes some assumptions that are specific to the Raspberry Pi

# The bootstrap cannot access a DOS partition embedded into a Plan9 partition
(9fat).
# The sd(3) driver cannot serve volumes from a partition table: we use
partfs(8) instead.
