Many thanks to everybody. Of course, I have read the Handbook, but there are very "wide" solution, not so specific as I tried to find. There is never said e.g. "Backup file /etc/fstab" or "After installation mergemaster your previously backed sendmail.cf with the new one to include your old changes". And I am so busy, that I tried to find such very specific type of information. Yes, yes, yes, it is bad idea to disturb you, but the list is the only "live" forum I have found. Once again, thanks a lot.
However, I upgraded that machine and all works fine (finally the sendmail, too). Except when I login, I get following errors (written twice): Sep 8 08:35:01 ns login: ROOT LOGIN (root) ON ttyv1 Sep 8 08:35:01 ns login: no modules loaded for `login' service Sep 8 08:35:01 ns login: pam_open_session: Permission denied What is it ? Is it I have misconfigured pam ? And how can I repair it ? Please, help.
