It is very easy to upgrade from Redhat 9 to the latest Fedora, but "minimal downtime" is the exact opposite of what you should expect. You should expect the upgrade to take about 10 hours (!!), and if you are upgrading with CDroms and not babysitting the machine all the time, expect 2 days of downtime... It appears that Fedora's upgrade process somehow sucks algorithmically, and during all these 10 hours Fedora churns your hard disk and spins up and spins down the CD-ROM. It looks to me like some sort of in-memory caching (most modern computers have huge amounts of memory which goes to waste during the installation process) and one time analysis of the disk's contents could have gone a long way of making the upgrade process quicker. Not to mention that I never understood why in Fedora you cannot upgrade a running system (like normal "yum update" just works). > cause less headache, since configuration files are > equal, however it doesn't seem to be server-stable (at > least according to biased redhay[1]) To me, it seems stable enough. -- Nadav Har'El | Sunday, Jun 11 2006, 15 Sivan 5766 [EMAIL PROTECTED] |----------------------------------------- Phone +972-523-790466, ICQ 13349191 |I am the world's greatest authority on my http://nadav.harel.org.il |own opinion. ================================================================= To unsubscribe, send mail to [EMAIL PROTECTED] with the word "unsubscribe" in the message body, e.g., run the command echo unsubscribe | mail [EMAIL PROTECTED]
