Finally got a build world/kernel to complete. Following a

It’s a ufs2 filesystem. I booted the 15-CURRENT
usb stick. It recognized it. I performed fsck on
it. No errors.
An attempt to mount it from the new kernel at boot is:
Mounting from ufs:/dev/gpt/FBSD15 failed with error 19.

Can anyone suggest the best way forward please?

Maybe this is a custom kernel without the label code.

It's an upgrade. It's 15 from ~11 mos ago. Yes a custom kernel. But
I'm using the same kernconf as before. Was label removed from generic
in the last 11 mos.?

Of course not. I have GEOM_LABEL in my kernconf. FWIW old vs. new
kernel indicates I gained
+acpi_sbl_wmi.ko
+bnxt_re.ko
+dummymbuf.ko
+gpioaei.ko
+if_iwx.ko
+if_mtw.ko
+if_rtw89.ko
+mac_do.ko
+p9fs.ko
+snd_dummy.ko
+umb.ko
+virtio_p9fs.ko
+wlan_gcmp.ko

and this was removed. No, root is not on gvinum
-geom_vinum.ko

What does '?' at
mountroot> prompt say?

nadda, nothing.

Does one of those work if you add 'ufs:/dev/' to the
front of each of the geoms listed? Most likely ada0p2 or nda0p2.

Indeed. It's nda0p2. But ufs:/dev/nda0p2 returns the same error 19.
I had to move kernel to kernel.new && kernel.old to kernel to get
here to write this response.

Thanks!
