A command such as the following:

causes reboot to invoke uadmin() with boot arguments including a quoted boot path. uadmin calls bootadm:

which creates a /boot/transient.conf file that loader cannot parse due to the quote characters around the bootpath.

One place that this occurs is when a stale boot archive is detected during boot. In that case filesystem/usr reboots the system using a command such as this.

Missing backslashes or apostrophes.

with apostrophes:

ok show boot-args
-B zfs-bootfs=rpool/ROOT/20191003,bootpath="/pci@0,0/pci1af4,2@4/blkdev@0,0:b" -B console=ttya
ok

yep, this is bug in bootadm.

bootadm testing:
