>Description:
Dear netbsd devels,


i got this error by building a release by:

#      link  bootxx_ffsv2/bootxx_ffsv2

### bootxx_ffsv2 size 7964 is larger than 7680
*** [bootxx_ffsv2] Error code 1


when build a release by:

        sh build.sh -m i386 -O ../obj/ -T ../tools -X ../xsrc -R ../release -j 
2 -U -u -r release releasekernel=XEN3_DOMU_NIELS iso-image

This happens on a freshly checked out current as at some of my tries several 
monthes before too.

I tried this build on different netbsd (4.x) with different checkouts and under 
cross building on Gentoo linux machines - with same result.

>How-To-Repeat:
cvs checkout netbsd-current and
sh build.sh -m i386 -O ../obj/ -T ../tools -X ../xsrc -R ../release -j 2 -U -u 
-r release releasekernel=XEN3_DOMU_NIELS iso-image

(i.e. without user changed kernel config)
sh build.sh -m i386 -O ../obj/ -T ../tools -X ../xsrc -R ../release -j 2 -U -u 
-r release iso-image

>Fix:
If i comment out bootxx_ffsv2 (as i dont need this boot option so this might be 
no real fix i assume) or change the var 7680 to that higher value - then i get 
a 
installable system for me, but i assume this problem would affect other users 
too when they try to build their own netbsd by following netbsd docs.
