The problem is this: I am writing a shell script which can run fsck on all UFS / ext2 /ext4 hard disk partitions listed in /etc/fstab. The script should be portable and be able to run no matter whether the OS running is FreeBSD or Linux. The only thing that matters is that the commands fsck_ufs / fsck.ext2 and fsck.ext4 are available. Ideally, the script should run only under single user mode, or else bail out immediately. Linux has a clean way to find out whether the system is in single user mode. I would think, no matter what others on this list have said, sysctl under FreeBSD too should have a variable for indicating single user mode. But there currently is not any.
