Seems like I've just been added, thanks.

Which is exactly what I would like to do - not to have to reinstall linux
on all our running nodes - just manage installation of LCG software on
them, without need to reinstalling linux.
In meantime I've browsed and read about LCFGng-lite - is this the way how
I can do it now?

Thanks.
I am going to do the installation, my only concern is to know how to avoid
reinstalling linux on our nodes, which are running and configured - just
some simple way to exclude the part of LCFGng installation where I should
reboot nodes and let them reinstall completely through network.
So: is it possible to install LCG-1 software on already configured linux
machines, using LCFGng-lite? (or any other mechanism).
Kindly thanks again for your time and replies.
