Don't say "dangerous" for _root_ user. Is there any purpose left for being= =20 root anymore? According to your logic, all root operations should be=20 disabled by some unknown undocumented sysctls because it is too dangerous= =20 to be the root.

It was not me. It was not majority= =20 of Unix sysadmins. Such kind of protection should be turned off by default= =20 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= =20 with standard MBR and sysinstall don't allow to write bootloader anymore.= =20 The only thing I not try yet in that situation was 'dd' - I was too lasy=20 to find needed byte. --=20 http://ache.pp.ru/ --VS++wcV0S1rZb1Fb Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (FreeBSD) iQCVAwUBQlCtAeJgpPLZnQjrAQLv/QQAqLHs+eZuYdKWcvUC7e0t6VlP5PDXcbVg 8sR3VZFJoqDN1FRDKx9h1euLCKsPLFp58e60XchoixXqhOUFwZYUbAhbacAzURqX nfvG5k33QFXnVb8K2PvuJUceYuLhKwV8LilCrPTyKXyac5WUJxlsYm3bjQtNbJBw 5kztyg2WFKs= =dfhh -----END PGP SIGNATURE----- --VS++wcV0S1rZb1Fb--
