Return to common.config CVS log

Up to [Development] / xfs-cmds / xfstests

This patche adds a new file in ./configs for each host that was
in the monolithic (ugly) common.config file.

the files have been auto-generated and might contain some quircks.

The in-source documentation has been updated as well.

# TEST_DIR -        scratch test directory that is in an already
#                   mounted XFS file system, needs to be be world
#                   writeable
# TEST_DEV -        device for file system containing TEST_DIR
# SCRATCH_DEV -     device you can make a scratch file system on
# SCRATCH_MNT -     mount point for scratch file system
#
# and optionally:
# SCRATCH_LOGDEV -  scratch log device for external log testing
# SCRATCH_RTDEV -   scratch rt dev
# TEST_LOGDEV -     test log device for external log testing
# TEST_RTDEV -      test rt dev
# TAPE_DEV -        the tape device for the xfsdump tests
# RMT_TAPE_DEV -    the remote tape device for the xfsdump tests
# RMT_IRIXTAPE_DEV- the IRIX remote tape device for the xfsdump tests
# RMT_TAPE_USER -   remote user for tape device
#
# - These can be added to known_hosts() below or a separate local
#   configuration file can be used (using the HOST_OPTIONS variable).
# - This script is shared by the stress test system and the auto-qa
#   system (includes both regression test and benchmark components).
# - TEST_DEV & TEST_DIR must be assigned.
# - this script shouldn't make any assertions about filesystem
#   validity or mountedness.
