hrm..we have a boot type of ZPOOL_COPY_BOOT_LABEL, I see several spots where it's assigned, but nowhere where it checks for that value... now i'm curious what actually copies the bootloader on a boot pool when replacing the disk

i'd expect something invoking installboot on the disk

oh..

sneaky

there's a syseventd script that calls a zfs script that calls bootadm install-bootloader

and that value doesn't actually appear to be used (anymore?)

jbk yes, the original sysevent script was using installgrub and installgrub has the copy feature (actually it is present in installboot as well, but I do not think it is that useful anyhow), I suppose, the original idea was to simplify raw boot slice handling or something like that.

the existence of that unused enum is what threw me off... by its name I thought it was triggering something
