Unabel to resurrect your old /etc/x

Hello,

I'm upgrading an 6.0-Beta1 installation with 6.0-Beta2.
It had already happened when upgrading to 6.0-Beta1.
There come lots of messageboxes with

Unable to resurrect your old /etc/csh.logout! Hmmmm.

Each messagebox pertains another file below /etc.

What should I do to make it able to resurrect those files?

Couldn't those messages be collected in a box that contains multiple
files, so I don't have to press Enter so often?
