# cpio archives

# The SVR4 "cpio(4)" hints that there are additional formats, but they
# are defined as "short"s; I think all the new formats are
# character-header formats and thus are strings, not numbers.
#0 string 070707 ASCII cpio archive (pre-SVR4 or odc)
# WARNING: The jump-to-offset value in the ASCII spio signatures below is a terrible hack.
# This keyword is not intended to be passed a string (%s), and doing so can open
# up the possibility of keyword injection by a malicious file. This works here though, because:
#
# 1) It would result in an invalid CPIO file (invalid size)
# 2) All valid keywords require more than 8 bytes, so a valid one can't be
# injected in the %.11s field.
