 While the first topic of this PR appears to be no longer valid (md5 now 
 supports -q), extended attributes are still not working in NetBSD 8.1:
 
  # newfs -O 1 /dev/rwd1a
  # mount -t ffs -o extattr /dev/wd1a /mnt/test/
  # cd /mnt/test && touch foo
  # setextattr system bar baz foo
  setextattr: foo: failed: Operation not supported
  
  # dmesg | tail -1
  /mnt/test: failed to start extattr: error = 2
  
  # config -x /netbsd | grep EXTA
  options         UFS_EXTATTR  # Extended attribute support for UFS1
 
 
 Curiously enough, while the original PR is from 2005, two commits[0] to 
 sys/ufs/ufs/extattr.h and sys/ufs/ufs/ufs_extattr.c from 2014 and 2016 can 
 be found, but I'm wondering if UFS_EXTATTR was even tested in the last 
 couple of years. FWIW, EA support has been removed from OpenBSD in 2005, 
 so maybe the code can be removed from NetBSD as well? It'd be nice to have 
 it working though :-D
 
 Thanks,
 Christian.
