sysinst is able to show them on the NetBSD install process, but my system is already installed, so I was looking for the very same as a standalone utility.

Indeed, I used it to prepare the partitions for NetBSD installation. However, I have 7 partitions on my hard disk and I need to know the order that NetBSD assigned as I intent to dump an image on one partition via dd utility. Without knowing the correct partition device (/dev/wd??) this would be very dangerous.

From the /etc/fstab I know the assigned order is not the same as they are defined in the RDB, as NetBSD root is 0 and swap 1.

Well, I have AmigaOS, GNU/Linux and NetBSD on the hard disk; so I cannot afford not using RDB. Thanks for the tip anyway, I didn't know it was even possible.

That's really nice! I do not need even to edit, just to print the NetBSD partition devices, their size and RDB name.

Thanks for the tips :)
