why vfstab file shows /opt fsck pass 2

vfstab file for my system is as follows:

#device device mount FS fsck mount mount
#to mount to fsck point type pass at boot options
#
#/dev/dsk/c1d0s2 /dev/rdsk/c1d0s2 /usr ufs 1 yes -
fd - /dev/fd fd - no -
/proc - /proc proc - no -
/dev/dsk/c0t0d0s1 - - swap - no -
/dev/dsk/c0t0d0s0 /dev/rdsk/c0t0d0s0 / ufs 1 no -
/dev/dsk/c0t0d0s6 /dev/rdsk/c0t0d0s6 /usr ufs 1 no -
/dev/dsk/c0t0d0s7 /dev/rdsk/c0t0d0s7 /var ufs 1 no -
/dev/dsk/c0t0d0s5 /dev/rdsk/c0t0d0s5 /opt ufs 2 yes -
swap - /tmp tmpfs - yes -

why fsck column for /opt is 2 while the rest are ether - or 1?

Sun Solaris manual says fsck pass indicates whether the file system is to be checked by fsck at boot time. A whole number indicates a yes. A dash or a zero indicates no.

So what does a 2 indicate? Why a 2 is placed in there for /opt by default? Does this mean anything differently for /opt?

fsck pass The pass number used by fsck to determine whether to check a file system. When the field contains a dash (-), the file system is not checked. When the field contains a value of 1 or more, the file system is checked; non-ufs file systems with a 0 fsck pass are checked. For ufs file ystems only, when the field contains a 0, the file system is not checked. When fsck is run on multiple ufs file systems that have fsck pass values greater than 1 and
the preen option (-o p) is used, fsck automatically checks the file systems on different disks in parallel to
maximize efficiency. When the field contains a value of 1,
the file system is checked sequentially. Otherwise, the
value of the pass number does not have any effect. In
SunOS 5.3 system software, the fsck pass field does not
explicitly specify the order in which file systems are
checked.

The fsck pass value
of 2 means that the file system will be checked, but not sequentially
