This file has no influence to how devices are being recognized. But as you mention it: Have you thought about adding labels to the partitions? It's a convenient way to abandon device names. Use the label to refer to the file system. You can find some informatio here: http://www.wonkity.com/~wblock/docs/html/labels.html https://www.freebsd.org/doc/handbook/geom-glabel.html It's easy to add them afterwards.

The installer _should_ be able to do this, but of course there is no problem to go to CLI and do it manually. It's not that this is a complicated task... :-) However, if a disk has been set as active, it doesn't matter as which device _type_ it's being recognized - it will boot, given that the BIOS (or in your case, the hypervisor) will transfer boot control to it. A partition marked as bootable will fulfill that requirement. From there on, labels are a convenient way to refer to the file system in further steps of the boot process (mounting root file system, mounting other file systems). -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
