Without this patch, the devuser element attempts to find public keys by
iterating over the string "rsa dsa". When two keys are grouped together
in quotes, a bash for loop treats it as a single key. You can see the
issue this causes when debug output is turned on:
+ for fmt in '"rsa dsa"'
+ '[' -f '/home/krinkle/.ssh/id_rsa dsa.pub' ']'
This is not a reasonably named key to look for, so this patch removes
the quotes so that the loop will look for id_rsa.pub and id_dsa.pub
separately.
