Apologies for my naivete in not expecting this. Could the ticket be
changed to a doc-bug?
Suggested wording for the sysupgrade (pkgsrc) manual page:
=3D =3D
.Sh RESTRICTIONS
The sysupgrade command may encounter issues if the userland version is newe=
r
than the kernel version, including shell command core dumps.
=3D =3D
I am uncertain whether rebooting sooner into the newer 11.x kernel
would make a difference;
and, this is not how I have run sysupgrade in the past.
This is already documented.
Note
Take care when upgrading across major releases - ensure your running kernel is never older than the userspace.
