>Description:
This problem is still present in 6.1. Here's a message I sent to one of the principal developers re 6.0rc2:

"I just attempted to install 6.0 RC2 on my old Thinkpad T42, another
old machine I use for experimenting. It has OpenBSD 5.1 installed,
which was done by telling their installer to use the whole disk, so no
GPT. I ask the NetBSD installer to use the whole disk and I still get
"device busy" when it attempts to newfs the filesystems. I can't do
the install. There really is a bug here, as I think you and I agreed
last March. When the installer is told "whole disk", it shouldn't
matter what is in the MBR; NetBSD should simply over-write it. The
installer actually says something to that effect, but it doesn't
behave that way."

This came up again today when I attempted to install 6.1 on a machine that I use for experimentation, where I'd previously installed FreeBSD, with a GPT partition table. Same thing -- the install failed with 'device busy'. This REALLY needs to be fixed, because it's an obnoxious bug that prevents people from installing NetBSD and it's been a problem with installer for too long.

 Hello,
 I tried to reproduce this bug with NetBSD 9.2 but I can't.
 I took a VM which had OpenBSD on it, and I installed NetBSD 9.2 from
 the iso file.
 The installation was working fine and the hard drive had a good size at the end.
 Maybe this bug was corrected between the 6.1 and 9.2 NetBSD version.
 Maybe you can close this bug?
 Best regards,
 Guillaume.

State-Changed-Why:
The reworked sysinst partitioning in netbsd-9 will offer to kill everything
that was previously on the disk for real and allows installation to
complete correctly.
