# __stc_assertion_start
#
# ID: inherit_001_pos
#
# DESCRIPTION:
# Test that properties are correctly inherited using 'zfs set',
# 'zfs inherit' and 'zfs inherit -r'.
#
# STRATEGY:
# 1) Read a configX.cfg file and create the specified datasets
# 2) Read a stateX.cfg file and execute the commands within it
# and verify that the properties have the correct values
# 3) Repeat steps 1-2 for each configX and stateX files found.
#
# TESTABILITY: explicit
#
# TEST_AUTOMATION_LEVEL: automated
#
# CODING_STATUS: COMPLETED (2005-07-04)

# The mountpoint property is slightly different from other properties and 
# so is handled here. For all other properties if they are set to a specific 
# value at a higher level in the data hierarchy (i.e. checksum=on) then that 
# value propogates down the hierarchy unchanged, with the source field being 
# set to 'inherited from <higher dataset>'.
#
# The mountpoint property is different in that while the value propogates
# down the hierarchy, the value at each level is determined by a combination 
# of the top-level value and the current level in the hierarchy. 
#
# For example consider the case where we have a pool (called pool1), containing 
# a dataset (ctr) which in turn contains a filesystem (fs). If we set the 
# mountpoint of the pool to '/mnt2' then the mountpoints for the dataset and 
# filesystem are '/mnt2/ctr' and /mnt2/ctr/fs' respectively, with the 'source' 
# field being set to 'inherited from pool1'. 
#
# So at the filesystem level to calculate what our mountpoint property should 
# be set to we walk back up the hierarchy sampling the mountpoint property at 
# each level and forming up the expected mountpoint value piece by piece until 
# we reach the level specified in the 'source' field, which in this example is 
# the top-level pool.
