Don't say "dangerous" for _root_ user. Is there any purpose left for being root anymore? According to your logic, all root operations should be disabled by some unknown undocumented sysctls because it is too dangerous to be the root. Better kill yourself than to be the root. > The reason it was possible in the past was because there was no protection > against this kind of thing. Does anybody asks for protection here? It was not me. It was not majority of Unix sysadmins. Such kind of protection should be turned off by default in case it even exists as the toy for some paranoid people. > Use boot0cfg and the FreeBSD bootloader instead? boot0cfg not works (I assume the reason is the same). I can't write FreeBSD bootloader because reinstalled Windows overwrite it with standard MBR and sysinstall don't allow to write bootloader anymore. The only thing I not try yet in that situation was 'dd' - I was too lasy to find needed byte. -- http://ache.pp.ru/ [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (FreeBSD) iQCVAwUBQlCtAeJgpPLZnQjrAQLv/QQAqLHs+eZuYdKWcvUC7e0t6VlP5PDXcbVg 8sR3VZFJoqDN1FRDKx9h1euLCKsPLFp58e60XchoixXqhOUFwZYUbAhbacAzURqX nfvG5k33QFXnVb8K2PvuJUceYuLhKwV8LilCrPTyKXyac5WUJxlsYm3bjQtNbJBw 5kztyg2WFKs= =dfhh -----END PGP SIGNATURE-----
