There is, and there isn't. :) Since UFS allows for hardlinks a single file may have multiple valid names. For instance: # cd /tmp # echo foo > f1 # ln f1 f2 484 -rw-r--r-- 2 root wheel 4 Feb 4 01:39 f1 484 -rw-r--r-- 2 root wheel 4 Feb 4 01:39 f2 However there's a dirty way to get at it via the vfs lookup cache entries hung off the vnode. Paul Saab showed me a delta that did something nasty like this, but I've got no clue as to where it is now. -- -Alfred Perlstein [alfred@freebsd.org] 'Instead of asking why a piece of software is using "1970s technology," start asking why software is ignoring 30 years of accumulated wisdom.'
