and restore segfaults too, IIRC. ;)
So I'm trying to understand - are attrs not applied because xfs_restore
terminates, or is everything fine other than the attrs missing when
it completes successfully?
iows, I get this when it fails:
QA output created by 350
Silence is golden.
+ATTR for /mnt/scratch/restore/dumpsrc/sparse0 DOES NOT match
+./tests/xfs/350: line 80: 18231 Segmentation fault (core dumped) $XFSRESTORE_PROG -F -f $tmp.stream1 -f $tmp.stream2 $RESTOREDIR 2>&1 >> $seqres.full
+restore failed
+(see /mnt/test2/git/xfstests/results//xfs/350.full for details)
and never get to the point of seeing if attrs are missing.
Anyway, a few other things below for the record...

so you need _require_scratch & _scratch_mkfs before this...

no need to recursively remove a file, but *shrug* :)

Just out of curiosity, is the root (-R) namespace relevant to the problem?
