See `man 7 symlink'. davidg also said it was not to use an inode for the symlink itself so every symlink in 4.4BSD are fast symlinks (as it was possible to use in FreeBSD 1.1.5.1). It don't like our behaviour either. Highly counterintuitive and deadly for sticky directories too where a user can't remove a link he made. -- Ollivier ROBERT -=- The daemon is FREE! -=- roberto@keltia.frmug.fr.net FreeBSD keltia.freenix.fr 2.2-CURRENT #1: Tue Feb 20 01:16:51 MET 1996
