6c1d30b737 Run tests with LVM_SYSTEM_DIR pointing to private root and /dev dirs. 
This makes the tests more reproducible and helps isolate
them from any existing LVM set-up.
* test/Makefile.in (abs_builddir): Define.
(init.sh): Emit definition of abs_builddir.
* test/lvm-utils.sh (unsafe_losetup_): Keep only the portable,
iterative approach.
(dmsetup_has_dm_devdir_support_): New function.
(init_root_dir_): New function.
Invoke init_root_dir_ for all but the first test.
* test/test-lib.sh (this_test_): Adapt to test-name change.
Invoke lvm-utils.sh much later (after tmpdir creation), and
only if the current test is not being skipped.
Remove useless abs_top_srcdir definition.
Rename t0->test_dir_rand_.
* test/t-lvcreate-pvtags.sh: Skip this test if the available
version of dmsetup is not new enough.
Use global, $G_dev_, rather than hard-coded "/dev".
* test/t-lvcreate-usage.sh: Make --verbose output more useful.

06b8fee542 Allow $DM_DEV_DIR envvar to override default of "/dev". 
* dmsetup/dmsetup.c (DEV_PATH): Remove definition.
(parse_loop_device_name): Add parameter: dev_dir.
Declare the "dev" parameter to be "const".
Use dev_dir, not DEV_PATH.  Handle the case in which dev_dir
does not end in a "/".
(_get_abspath): Declare "path" parameter "const", to match.
(_process_losetup_switches): Add parameter: dev_dir.
Pass dev_dir to parse_loop_device_name.
(_process_switches): Add parameter: dev_dir.
Pass dev_dir to _process_losetup_switches.
(main): Set dev_dir from the DM_DEV_DIR envvar, else to "/dev".
Call dm_set_dev_dir.
* lib/libdm-common.c (dm_set_dev_dir): Rewrite to be careful
about boundary conditions, now that dev_dir may be tainted.
* man/dmsetup.8: Mention $DM_DEV_DIR.
