Don't blame the software.

Yup. You (or more properly, Amanda) _told_ it to. See the output of 'mount(8)' for the names of all the mounted filesystems on your machine. *NOTE*WELL* that '/proc' is *not* a separate filesystem. It is merely a _directory_ with a bunch of 'special' files in it. The 'error message' is accurate -- but it is _just_ a 'warning', and -- in *this* circumstance -- _totally_ innocuous. If you want to suppress generation of that error, simply add an '--exclude' for /proc to the Amanda run. _______________________________________________ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "freebsd-questions-unsubscr...@freebsd.org"
