If you upgrade via the installer's (U)pgrade option then this *does* write new boot blocks. You may get lucky if the old /boot doesn't get overwritten, but it's a good idea not to count on this.. Also note that if your 'a' partition starts too high into the disk, you might have problems with some updates (e.g. to -current / 5.3 where the boot loader grew). For Windows users having trouble getting partitions shrunk sufficiently to start OpenBSD early enough in the disk, PerfectDisk (commercial but there's a free trial) usually works. My dual boot laptop had space for an msata ssd so I put the OpenBSD boot there, Windows boot on the HD, and use bios boot select to switch between them instead..much more straightforward :)
