# Description:
# zdb -l exit codes are correct
#
# Strategy:
# 1. Create a pool
# 2. Overwrite label 0 on vdev[1] with dd
# 3. Create an empty file
# 3. Run zdb -l on vdev[0] and verify exit value 0
# 4. Run zdb -l on vdev[1] and verify exit value 1
# 5. Run zdb -l on the empty file and verify exit value 2
