(Pardon the bad "english"). He wouldn't be able to clobber the UFS partition if he was booted from it. So he needs to boot from something else. Supposing that, then yes, you could do this. You'ld need to boot from some other media -- a bootable USB stick perhaps, or an installer DVD image, the image for either of which can be downloaded from ftp.freebsd.org Cheers, Matthew --DD1sgNVSXVVSngHEEwRbB8E8J2XMm4m8Q-- --6NwmKuGCXC7b5D7mhhdi3FOqpAvGpGQbB Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- iQJ8BAEBCgBmBQJYDpUtXxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXQ2NTNBNjhCOTEzQTRFNkNGM0UxRTEzMjZC QjIzQUY1MThFMUE0MDEzAAoJELsjr1GOGkATGRQP/jZVQp6PwXMuJxmB2KKuVzDu O/oyz+Ep/ha4jugrq5VbdqsBO8+te9R3975xx1z1RjnrTRQPR4mf0VwaDgm1zqS8 NyhQrygvrCKHczUqUDkwG4C02jTU4DC2lNI2i175riVzVu1SVyBoA1ng4+9PzBEq MuSyiHnGGkhoYtBsFUm0ANXKS3Ueknvlr05ize6bsYhscV4kOPex3SXDQJY2dkT6 Jq6YHOoLNg8um9ROEp0/a+uuwEAWhFmIeFxDoNrYFGh29oyCKBDsfChvU7azwQsD DlGhGv05JHvEB0VXRj3mZMvwnz1AherWIarGM1a8sbXr8vwIdb0/HHOmE+jgFcsB 2GHw+jfbJjzNwmpc/3nzcIa8FdU66JdhkXlql3d/L5otRYqeikWNlfFef42DUNqt EcNRPmpuqV3/4GL0dud/mkImNRZueq7LiV220sH27qyXjN1TptcKLlytwstY79th iDAe4/FIXGB04hWHa98zH9msEvJcVWTTB9t3gqAlkx2tS4exe0uobXPhxByE2dSB ctQHiVCBzhkhXaazLiIuHL6H23+wkurka2DSLgfK62Zob+QFyR4VQsIk479Kqfl0 TUf+6EFtfeTfiNxwCMGCgNXPjZv6KG/WpQrG8Nz1403pUHT2HY9KHFolXS9xswUK fOwhccj5Thq95B3M6Vky =9wq8 -----END PGP SIGNATURE----- --6NwmKuGCXC7b5D7mhhdi3FOqpAvGpGQbB--
