Hello all,
I know this might be a weird place to ask, but thought some of you
may have some insight. I'm setting up four raspberry pis for an
installation to just loop through videos on four TVs with vlc and
openbox.
Do you think I could set up the image on one pi, and then clone them
on other sd cards for the other 3 pis? There should be no issues with
doing that, right?, especially since I don't plan on giving them
internet access. The pis all have the same size sd card too, making
this even easier. I think I'm just going to throw 32-bit arch linux
arm one of the pis, set one up the way I want, and then clone them
for the other pis.
The only problem I can see (assuming using dd to copy) is that all USB
cards can vary somewhat in size even for the same size (ssd do this
too). You may wish to make your master copy partition just a little
bit small. Even a network should not be a problem as I think DHCP can
be set up to make sure all node have unique names as well as IPs. So
streaming from a central server or making content changes there would
not be out of the question.

I'm doing something similar, though my Pis are networked. I set up one
the way I want, then use a script to
back it up to my laptop, then another script to copy it to SD cards for
the copies. I tweak the hostname
on the laptop before writing individual cards. Basically, I set up
partitions on the SD card making the
root partition fill the card, then use the 'sudo cp -x' command to copy
all the individual files. This
avoids any problem about the variations in size of the cards. If anyone
wants to pursue this, I'm
happy to email my scripts and other notes off-list. For the case above,
it's just a case of running
the two scripts, download the original card, then duplicate to the copies.
