# Hack for developer testing

# If you set $samples to a directory containing smartctl output text files,

# we will use them instead of running smartctl on the vdevs. This can be
|
|
# useful if you want to test a bunch of different smartctl outputs. Also, if

# $samples is set, and additional 'file' column is added to the zpool output
|
|
# showing the filename.

|
|
# is chosen quasi-sequentially (based off our PID). This allows us to return
|
|
# a different filename every time this script is invoked (which we do for each
|
|
# vdev), without having to maintain state.
