# IMPORTANT: We need to keep a common base syntax here
# because some of these hooks/scripts need to run under
# the klibc shell or even busybox's ash - therefore, the
# following constraints should be enforced:
# variables should be quoted and bracketed "${SOMEVAR}"
# inline execution should be done with $() instead of backticks
# use "x${var}" = "x" to test for nulls/empty strings
# incase of embedded spaces, quote all path names and string comaprissons
