  Modified files:
    usr.bin/su           su.c 
  Log:
  Do not chdir(2) until after setuid(2), otherwise "su - username" would fail
  when root doesn't have the permission to enter target user's home directory.
  If set, PAM environment variable HOME will be used in chdir(2) instead of
  pwd->pw_dir, this allows pam_chroot module to continue to function.
