simply `installboot $(df -h / | grep -o -E '[ws]d[0-9]+')`
There's definitely a difference between using the device name and the
DUID:
[weerd@pom] $ doas installboot -v `awk -F. '/ \/ / {print $1}' /etc/fstab`
Using / as root
installing bootstrap on /dev/rsd14c
using first-stage /usr/mdec/biosboot, second-stage /usr/mdec/boot
5c0d9a38cc895a7d: softraid volume with 0 disk(s)
5c0d9a38cc895a7d: installing boot loader on softraid volume
/usr/mdec/boot is 6 blocks x 16384 bytes
[weerd@pom] $ doas installboot -v $(df -h / | grep -o -E '[ws]d[0-9]+')
Using / as root
installing bootstrap on /dev/rsd14c
using first-stage /usr/mdec/biosboot, second-stage /usr/mdec/boot
sd14: softraid volume with 1 disk(s)
sd14: installing boot loader on softraid volume
/usr/mdec/boot is 6 blocks x 16384 bytes
sd0a: installing boot blocks on /dev/rsd0c, part offset 144
master boot record (MBR) at sector 0
partition 3: type 0xA6 offset 64 size 1953520001
/usr/mdec/biosboot will be written at sector 64
So if I were you, I'd continue using the device for now.
Cheers,
Paul 'WEiRD' de Weerd
