# DESCRIPTION:
# Test that zpool status colored output works.
#
# STRATEGY:
# 1. Create a pool with a bunch of errors and force fault one of the vdevs.
# 2. Look for 'pool:' in bold.
# 3. Look for 'DEGRADED' in yellow
# 3. Look for 'FAULTED' in red

#
# Luckily, awk counts the start and end escape codes as separate fields, so
# we can easily remove the vdev field to get what we want.
