With beta2, pcmcia interfaces came up automatically at boot (I'd selected the option to enable them at boot during install) on my laptop. After upgrading to beta3, they're no longer enabled automatically, even though ifcfg-eth0 has ONBOOT=yes in it I'll do a clean install tonight and see if it's just weirdness caused by a beta -> beta upgrade.
I did a clean install of beta3. Same problem -- although I told it I wanted my interface enabled at boot, it's not.
