>Description:
Attempted to use sysinst to install NetBSD on a Sun Netra 240 with a 73 GB SCSI disk. Rendered the system unbootable with bootblock saying
"Inode not directory."
This may be due to too large "/" filesystem.
Reducing "/" from 56 GB to 1 GB made the installation succeed.
OPB version is 4.30.4.a.

>How-To-Repeat:
Install from NetBSD-daily ISO image.

>Fix:
The cause of the error message is not obvious to the end-user, but
is likely due to firmware limitations.
It would be good to improve the boot block error message is to hint at the cause and possibly if sysinst could warn the user if "/" exceeds 4 GB on this port.
