You are aware that fedora 10 is a dead version .
It hit it's END OF LIFE last year
There will NEVER be any new software for it .
There is NO support for 10
There never will be any updates to it .
New software from other places( like firefox4 ) WILL NOT run on it( ff 3.6.13- the current might not even run).
and even installing rpms form the OLD fedora10 repo will require that you edit yum to point to the HISTORICAL archives
that post is not keep up to date so you will have to correct for 10 instead of 9
fedora uses cron for the log rotation default is 30 days
not many things ,that have not already , need a new script
1)software update ?
but seeing as 10 has not had any released in over a year and that there will NEVER be any ,that is NEVER to be an issue in 10
2)running ClamAV for MS viruses on a mail server
that is already taken care of by a daemon
this one maybe
adding new users to an extended network
adding and restricting there SELinux permissions for the new users
-- that can be a pain if you need to do it for 50 new users
