 You mean UFS2?  :)
 
 % mount
 /dev/ad1s3a on / (ufs, local)
 devfs on /dev (devfs, local)
 /dev/ad1s2d on /home (ufs, local, soft-updates)
 /dev/ad1s3d on /tmp (ufs, local, soft-updates)
 procfs on /proc (procfs, local)
 
 (The test was under /home.)
 
 Thanks for the info.  In any case, cat do misbehave when both directories a=
 nd
 files are passed as parameters, as it doesn't cat anything else after the
 directory:
 
 % cat -n Makefile Makefile . Makefile Makefile
      1  #       @(#)Makefile    8.1 (Berkeley) 5/31/93
      2  # $FreeBSD: src/bin/cat/Makefile,v 1.7 2001/12/04 01:57:37 obrien E=

 $ 3
      4  PROG=3D   cat
      5
      6  .include <bsd.prog.mk>
      1  #       @(#)Makefile    8.1 (Berkeley) 5/31/93
      2  # $FreeBSD: src/bin/cat/Makefile,v 1.7 2001/12/04 01:57:37 obrien E=

 $ 3
      4  PROG=3D   cat
      5
      6  .include <bsd.prog.mk>
      1  !g
           .cat.1.gz=D9=E5=F8.=D8=F6/~...src/usr.bin/cat%
