Thanks for this suggestion .. I'm embarrassed it didn't occur to me.
Unfortunately, it doesn't seem to work in this case either.  Even with
ca-certificates in the nfsroot I'm still getting cert errors during
the 'updatebase' task.

Interestingly, once the install is done if I break out to the shell,
both `apt list --installed | grep ca-cert` AND `$ROOTCMD apt list
--installed | grep ca-cert` show the package is installed, and running
`apt update` at that point produces no errors.

I'm not really sure what's going on there .. I would have expected the
environment to be no different at those two stages.
