Thank you very much for your answers.
I tried as you mentioned.
More script is attached just below.

I removed the line at fstab.
But the follwoing error message came out.

.....
/etc/rc: WARNING: No swap space configured!
.....

Yes, I manually did "mdsetimage" before vnconfig -u.
This problem was cleared!

Building databases...
kvm_mkdb: /netbsd: No such file or directory
.....

kvm_mkdb was exeuted at initial time, and it need /netbsd.
And some command like "netstat -rn" need /netbsd.
# netstat -rn
netstat: /netbsd: No such file or directory

> Do they output any error messages?
# useradd -m -c "Boo Geum Jung" -G wheel bgjung
useradd: pw_mkdb failed: No such file or directory
# vipw
vipw: the passwd file is busy.
