Linux Changes, July 2006

This page is for sharing information regarding the Fedora 5 upgrade during summer 2006.

Test machines

There are currently 2 designated test machines. A regular office workstation is available (f5beta1) and a computational sensor style machine (f5beta2).

sendmail client configuration
Our fedora 5 workstation installation will contain a new sendmail client configuration as part of the continuing department email infrastructure upgrade process. This should be completely transparent to users. I announce this here simply to notify users that if they notice a problem or unexpected email behavior when sending email from a fedora 5 workstation it should be reported to labstaff so it can be addressed promptly. The configuration has now been installed on the two beta machines for testing before deployment. note: If your email client does not automatically append a fully qualified domain name (FQDN) to email addresses before sending mail you should consider updating your local aliases to include them ('somebody@somewhere.com' rather that just 'somebody'). In most cases the sendmail service will attempt to figure it out for you when mailing to local addresses but it is better practice to explicitly provide it.

Pre-deployment Testing and Observations

gcc version changes
Fedora Core 3 uses gcc 3.4.4 but Fedora Core 5 will upgrade gcc to version 4.1. While testing recompilation of your source code here is a link to the changes, features, and fixes you'll find in gcc 4.1 http://gcc.gnu.org/gcc-4.1/changes.html

POSIX: sort and tail
Warning: sort +N and tail +N no longer work - use sort -k +N and tail -n +N instead.

testing fedora 5 desktops
It appears to be safe to login to the console of the test machine f5beta2 to test-drive the latest gnome and kde desktops in terms of not destroying your current desktop settings when logging back in later on a fedora 3 machine. I have only performed a quick test on an account that did not have a significantly customized desktop, but things seem cross compatible. I would avoid making custom changes to the fc5 version before the actual rollout though. You will notice a Link to Old Desktop icon added. Gnome test was pretty uneventful but the first fc5 KDE login hesitated for a minute or two during "init system services" and then complained about a SIGSEGV signal 11. Logging out and back in again, with a KDE session, the problem went away so it appeared to be a one time personal config update issue.
