+ the "rootsbindir" can now be specified at configure time
+ mount.cifs now supports the -s option by passing "sloppy" to the
kernel in the options string
+ cifs.upcall now properly respects the domain_realm section in krb5.conf
+ unprivileged users can no longer mount onto dirs into which they
can't chdir (fixes CVE-2012-1586)
