	Welcome to the NetBSD/sun3 39915 installation program.
	
	This program is designed to help you put NetBSD on your disk,
	in a simple and rational way.  You'll be asked several questions,
	and it would probably be useful to have your disk's hardware
	manual, the installation notes, and a calculator handy.
	
	As with anything which modifies your disk's contents, this
	program can cause SIGNIFICANT data loss, and you are advised
	to make sure your data is backed up before beginning the
	installation process.
	
	Default answers are displayed in brackets after the questions.
	You can hit Control-C at any time to quit, but if you do so at a
	prompt, you may have to hit return.  Also, quitting in the middle of
	installation may leave your system in an inconsistent state.
	
	Proceed with installation? [n] y
	Cool!  Let's get to it...
	Remounting root read-write...
	panic: blist_meta_fill: allocation too large
	syncing disks... done

>How-To-Repeat:
	Try to install NetBSD/sun3 -current using tmesh using the miniroot.fs.
>Fix:
	No idea.
