This is totally non-programming question, but I am out of the ideas right now. This is a task which I need to accomplish, but it seems there is no vaild answer in the Google. I mean, who would want errors gone during boot time when they are quite important.

I hope that somewhere in this forum I can found devoted Linux user who knows how to do it.

By now the best solution I came up was to look through all initial scripts and commented the lines which throws errors.
