I recently upgraded an older machine of mine this past weekend (to the latest and greatest 9.10).
The install went smooth, but the OS required ALOT of work after the upgrade... I will be reverting back to 9.04.
- /etc/sudoers - I had to edit, just to use sudo
- 3D desktop effects ran... but was very choppy.
- 90% of my custom tweaks/mods were shot to hell (SSH, apache2, squid... list could go on)
So for now I will be going back to 9.04, on this machine. Keep in mind that this is a AMD 1.6 Ghz, 3 Gigs of RAM, old Nvidia PCI GFX card...
On a newer machine 9.10 would be better suited... but for older systems, I would not recommend upgrading. Thank god this was just a test machine...
