question on filesystem

I heard that if normal users were allowed to create device files by mknod, security problem would be happened. what problem do you think will happen?

and It is a really bad idea to use fsck(1M) on a disk partition that
is mounted. For example it would be a mistake to run # fsck /dev/rdsk/c1t1d0s6 if /home is mounted. why is it a bad idea?

last, sys admin has made a change to the filesystems on FreeBSD server. can normal user find out what is changed? and how?

MKFS.MINIX(8)						       System Administration						     MKFS.MINIX(8)

NAME
mkfs.minix - make a Minix filesystem SYNOPSIS
mkfs.minix [-c|-l filename] [-n namelength] [-i inodecount] [-v] device [size-in-blocks] DESCRIPTION
mkfs.minix creates a Linux MINIX filesystem on a device (usually a disk partition). The device is usually of the following form: /dev/hda[1-8] (IDE disk 1) /dev/hdb[1-8] (IDE disk 2) /dev/sda[1-8] (SCSI disk 1) /dev/sdb[1-8] (SCSI disk 2) The size-in-blocks parameter is the desired size of the file system, in blocks. It is present only for backwards compatibility. If omit- ted the size will be determined automatically. Only block counts strictly greater than 10 and strictly less than 65536 are allowed. OPTIONS
-c Check the device for bad blocks before creating the filesystem. If any are found, the count is printed. -n namelength Specify the maximum length of filenames. Currently, the only allowable values are 14 and 30. The default is 30. Note that kernels older than 0.99p7 only accept namelength 14. -i inodecount Specify the number of inodes for the filesystem. -l filename Read the list of bad blocks from filename. The file has one bad-block number per line. The count of bad blocks read is printed. -1 Make a Minix version 1 filesystem. -2, -v Make a Minix version 2 filesystem. -3 Make a Minix version 3 filesystem. EXIT CODES
The exit code returned by mkfs.minix is one of the following: 0 No errors 8 Operational error 16 Usage or syntax error SEE ALSO
mkfs(8), fsck(8), reboot(8) AVAILABILITY
The mkfs.minix command is part of the util-linux package and is available from ftp://ftp.kernel.org/pub/linux/utils/util-linux/. util-linux June 2011 MKFS.MINIX(8)
