I installed Red Hat 8 last night on my aging 7.1 box. The install went OK (although an upgrade wouldn't work since I'd installed to many things via tarballs or something, so I had to tar up my home directory) and the new installer is really pretty. There's a couple things to fix afterwards:

XMMS won't play MP3s. Red Hat did this on purpose, to get around potential DMCA concerns. I think. Anyway, go to freshrpms.net and get the MP3 plugin RPM for XMMS. Works like a champ.

Next issue is that the sound won't work if you happen to have a motherboard with onboard audio and an add-on soundcard. I have an Asus K7M266 mainboard, and it has some sound chip on it (I forget which kind). I have it disabled in the BIOS but Red Hat 8 apparently detected it during install and decided that it was my "main" soudnb card. Of course, since it's disabled there's no sound. I have the Soundblaster modules loaded, however.

The fix is in /etc/modules.conf. My original conf file looked like this:

alias parport_lowlevel parport_pc
alias eth0 tulip
alias scsi_hostadapter aic7xxx
alias sound-slot-0 cmpci
post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null 2>&1 || :
pre-remove sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null 2>&1 || :
alias sound-slot-1 emu10k1
post-install sound-slot-1 /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null 2>&1 || :
pre-remove sound-slot-1 /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null 2>&1 || :
alias usb-controller usb-uhc

It should look like this:

alias parport_lowlevel parport_pc
alias eth0 tulip
alias scsi_hostadapter aic7xxx
alias sound-slot-0 emu10k1
post-install sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -L >/dev/null 2>&1 || :
pre-remove sound-slot-0 /bin/aumix-minimal -f /etc/.aumixrc -S >/dev/null 2>&1 || :
alias usb-controller usb-uhci

Just get rid of all the 'sound-slot-0' stuff and make the Soundblaster-centric stuff sound-slot-0 and you're back in business.

BTW, the new Bluecurve "stuff" (I don't want to call it just a theme, since it seems to be more than that) looks awfully pretty. But I get the feeling that it's been done before. It's nice, though. A WinXP user would be right at home and a Mac OS X user would hate it.
