I propose a change to the document 'SHARI Allstar Node Setup and Configuration Guide'.? on page 2 the required hardware list suggests a SD Card 16G or larger.? this should be changed to 4G required and larger is optional.? from the Allstar Handbook (found here?? and other places) on page 8...
SD Cards
The information below is from Arm Allstar by Doug Crompton.
Just a reminder though that the read/write performance of the SD cards in a Linux application like Asterisk Allstar is immaterial after boot. So using a faster card is not going to make your system run faster. It would allow faster creation of the initial image and possibly faster boots (measured in a few seconds) but in most cases it would not be practical economically to purchase a super fast SD card. The speed which a card writes is also heavily effected by the type of writer (usb2/3) and the SW used to write. So while the relative differences in these tests might be valid the absolute values of these tests could differ greatly based on the hardware and SW used to write. Tried and true my choice is still the SanDisk Ultra but I am sure there are other cards in it's class that could be used. Also as I mentioned on the web page unless you have a compelling reason it is NOT a good idea to expand the filesystem on these cards after installing the image. Doing so makes total image backup a time consuming process especially on 16GB and larger cards and does nothing to improve performance or longevity
-----------
furthermore,
the image from the current repository at hamvoip.org expands to less than 4G.? it does not auto expand on your SD Card leaving anything above 4G unused anyway.
