See 1686f9ab "xfstests: Introduce a results directory" which explains just where this variable came from and what it's for... So that's probably why it's undocumented; I don't think it was envisioned as a configurable. As for consistency... patch sent for the typo. If the functionality is needed, just make sure it works right if you set it manually, update the user docs, & send a patch. > There are a bunch of inconsistencies, which I've chalked up to > historical accidents and a desire to not break compatibility with > developers' test runners. You mount the $SCRATCH_DIR on SCRATCH_MNT $SCRATCH_DEV you mean. ;) I don't think there's any real resistance to fixing things that really need to be fixed, but this one doesn't seem too critical. OTOH, adding an alias from SCRATCH_MNT to SCRATCH_DIR for consistency could surely be done if anyone cared enough to send the patch. > but you mount $TEST_DEV on $TEST_DIR, for example.

(No doubt docs could be improved, but we can do that by sending patches.) :) -Eric
