Ok, it seems that busybox tr does not actually support symbolic ranges. Rather than add a first user of awk it seems simpler to manually expand the character ranges. Specifically as the specification says the following:
"The hexadecimal values "a" through "f" are output as lower case characters and are case insensitive on input." we can simply map A-F to a-f and cover all valid cases. @manjo -- I have uploaded this fix to my ppa:apw/ubuntu/initramfs-tools- test for testing.
