After this morning's weekly upgrade, entropy and entropy.conf were upgraded. Afterwards, I ran another upgrade just to make sure everything was operational and in sync. It asked me if I wanted to downgrade the three packages I have installed from Portage.
So, I went to the new entropy.conf to re-enable ignore-spm-upgrades. The parameter is no longer included, Can I add it back on my own and is it still supported? If not, how can I manage this?
