Hi:

I compiled a new kernel and put it in the root. When I tried to delete it,
I got error messages.

/> ls -l netbsd
-r-xr-xr-x  1 root  wheel  1064524 Dec 20 12:59 netbsd
/> rm netbsd
remove netbsd? y
rm: netbsd: Operation not permitted
/> chmod +w netbsd
chmod: netbsd: Operation not permitted
/> 

I even tried to delete it in the single user mode, but it is still not
working. Anyone can help? Thank you in advanced.
