Probably the message is generated by the kernel and cannot be ignored. Try this: % perl use POSIX qw/:fcntl_h dup2 setsid/; if (fork) { exit; } setsid; my $fd = POSIX::open "/dev/null", O_WRONLY or die "Can't open /dev/null: $!\n"; dup2 $fd, 0; dup2 $fd, 1; dup2 $fd, 2; sleep 5; system "sudo mount /dev/fd0 /mnt"; % # wait for an error within 5 seconds or so If no error appears, I think you forgot the / on /dev/null up there :-) Make sure to unmount the floppy afterwards. If there is an error, it proves that it was/is a kernel message. -- Josh > > > > Thanks, > Charles > > > _______________________________________________ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "freebsd-questions-unsubscribe@freebsd.org"
