 I'm still having trouble understanding why people think sudo is
safer, even where it is configured to require a password (I accept
that restricting it to specific commands is safer, but probably
inconvenient in BLFS).  In OSX I have to type my user password the
first time I sudo, but then ISTR I can continue to sudo for a period
of time without repeating the password.

 But then, people have been known to use empty passphrases with
subversion - I can see the convenience (e.g. in svn blame), but it
doesn't mean it's a good idea.
