Ok, I'll change that.

# Prepare to run a fstest by initializing the global seq, seqres, here,
# tmp, and status variables to their defaults, importing common
# functions, registering a cleanup function, and removing the
# $seqres.full file.
#
# The list of group memberships for this test (e.g. auto quick rw) must
# be passed as arguments to this helper.  It is not necessary to name
# this test explicitly as a member of the 'all' group.
