Hi, Before I cast my lot in with a KDE4-based system, I'd like to leave my 11.1 bridge unburned. If I install 11.3 and have it use the same /home as my 11.1 installation, will they coexist peacefully or interfere with each other? I doubt I'd try it, but what about the same question for /var?

Since you say 'cast my lot in with KDE4' I understand that your 11.1 system mostly uses KDE 3. From the KDE3 & 4 standpoint: In this case KDE3 in 11.1 and KDE SC 4.4 in 11.3 should coexist, because KDE 3 stores its data in ~/.kde, whereas KDE 4 uses ~/.kde4. Since the KDE 3 packages still present in 11.3 are at the same KDE 3.5.10 as was released with 11.1 (even if you updated using OBS KDE:KDE3) you should be able to switch back and forth without the .kde stuff being changed incompatibly. Regarding 11.1 KDE 4.1 vs 11.1 KDE 4.4: Since these share the same $KDEHOME (as above) KDE 4.4 will update config files in a forwards-incompatible way that will cause problems if you try to use them later in KDE 4.1. I don't see any reason a private user would want to keep 4.1 so if this is an issue, update the 11.1 KDE 4 to 4.4 using KDE:Distro:Stable from the OBS. I can't speak for anything !KDE you may be using that may update its configuration in /home the first time you run it under 11.3 - tread carefully.

I doubt I'd try it, but what about the same question for /var?

For homes one recommended option is to have separate relatively small home partitions on each system and larger shared partition with all "real" user stuff (Documents, Downloads, Pictures and so on). Then soft-link these directories to /home of each system. As far as systems are different Open SuSE versions, it works fine. If you have other system (e.g. Kubuntu) that allocates user and group IDs differently it might be more tricky. /var is interesting one... e.g. /var/logs, /var/admin, /var/cache... I wouldn't try it either. Regards -- Mark Goldstein -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

IIRC, kde3 stuff is under ~/.kde and kde4 stuff is under ~/.kde4. Nonetheless I would suggest you back up the respective .kde dirs before you switch your desktop between KDE3 <> KDE4.

/var is interesting one... e.g. /var/logs, /var/admin, /var/cache... I wouldn't try it either.

I second it. -- Arun Khan -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

Thanks, folks. I think for evaluation purposes, I'll just make a secondary home directory and use that. Ultimately, I can't hang back on 11.1, anyway, but I have so very many tweaks and customizations to my beloved KDE 3 environment, I don't feel like being pitched into the sea of KDE 4 without some sort of safety net.

I think that would be a waste of space - and potentially introduce unnecessary inconsistencies for any _real_ data you need to deal with (such as browser configurations, e-mail, etc.). I ususally just have some bind-mounted directories for each involved user, such as: # OS specific redirection mounts: /home/gnu/.OS/sle11sp1/.rpmmacros /home/gnu/.rpmmacros none bind 0 0 /home/gnu/.OS/sle11sp1/.rpmrc /home/gnu/.rpmrc none bind 0 0 /home/manfred/.OS/sle11sp1/.config /home/manfred/.config none bind 0 0 /home/manfred/.OS/sle11sp1/.gconf /home/manfred/.gconf none bind 0 0 /home/manfred/.OS/sle11sp1/.gkrellm2 /home/manfred/.gkrellm2 none bind 0 0 /home/manfred/.OS/sle11sp1/.gnome2 /home/manfred/.gnome2 none bind 0 0 /home/manfred/.OS/sle11sp1/.icewm /home/manfred/.icewm none bind 0 0 /home/manfred/.OS/sle11sp1/.kde /home/manfred/.kde none bind 0 0 /home/manfred/.OS/sle11sp1/.kde4 /home/manfred/.kde4 none bind 0 0 /home/manfred/.OS/shared/.kde/share/apps/amarok /home/manfred/.kde/share/apps/amarok none bind 0 0 /home/manfred/.OS/sle11sp1/.local /home/manfred/.local none bind 0 0 /home/manfred/.OS/sle11sp1/.mcop /home/manfred/.mcop none bind 0 0 /home/manfred/.OS/sle11sp1/.rpmmacros /home/manfred/.rpmmacros none bind 0 0 /home/manfred/.OS/sle11sp1/.rpmrc /home/manfred/.rpmrc none bind 0 0 /home/manfred/.OS/sle11sp1/Desktop /home/manfred/Desktop none bind 0 0 I then have the version specific stuff in a separate directory structure below ~/.OS/<version>, and store the shared/common stuff below ~/.OS/shared .
