Most software is released before it is ready for prime time. If you have used computers for any length of time you may have encountered some of the issues as a result. An icon that is a question mark. The blue screen of WindowsME® at a trade show. The sluggish reboot. And so on.
Many seasoned network administrators wait a considerable time to embrace new versions of operating systems.
When implementing Microsoft® server software, I often recommend waiting for the first service pack.
Cost and time issues typically prevent a thorough and complete error free build on release day. Fedora® 13 still had several issues on release day. As a result of the latest updates I find that I have only one minor issue with Fedora 13 x64 at this time. The issue only effects Intel® Core i3, i5, and i7 based processors. This issue is a minor nag error message at boot time that does not have any actual impact on system stability or performance. It is merely an annoyance. The error is:
alg: hash: Failed to load transform for ghash-clmulni
All of the applications and daemons that I use on my workstations and servers are behaving well. The performance of the current kernel is fast and stable. If you have been waiting to try Fedora, this may be a good time to take the plunge.
