# this test checks that old (v1, pre 8.34.0) imfile state files are
# properly read in. It is based on imfile-readmode2-with-persists.sh,
# where the first part before the shutdown is removed, and an old state
# file is populated. Note that in contrast to the original test the
# initial set of lines from the input file is missing - this is
# exactly what shall happen.
# This is part of the rsyslog testbench, licensed under ASL 2.0
