# test-log-rollover.sh - test how grabserial performs log-rollovers
#
# to do:
#  should test with  and without split-lines  -z
#  should test with and without rotation rounding (rotation units)
#    '-R 10s' or '-R 2m'
#  should test with ping on target:
#    start a 'ping -i 0.05 localhost' on the target, for high-frequency output
#
#  - should check that line boundaries are observed when not using -z
#  - should check that log rotation is at even boundaries when using rounding
#  - should check that no data is lost during rotation
