ALSO. 

I have buy some means got as far as sucessfully downloading the three packages ( base, kernel and packages) .  Also atempting to install the afformentiond packages.  However the kernel package fails with the message rm: argument list too long.  I have also had base fail with .mkdir: /var/cache/opnsense-update/75470: Too many links


Does anyone have thoughts on this issue please.
