How to set the default group for a new user in SuSE.
 

I recently purchased SuSE 9.1 pro. ( An impulse purchase at Best Buy )

I made a dumb mistake during the install. I must of set the default group for new users to be 'users'. The next day, I realized that this meant that one user could read another users files.

I corrected the mistake to the default group manually, but I'd like to know how to undo my mistake.

The yast setup has a drop down box to change this but you can only choose from a pre-made group. When I was using Mandrake linux, each user had a group by the same user name created so this wasn't a problem.

How is the default user supposed to be set with the SuSE distribution, so one doesn't have to manually create a group each time you create a new user.

Unrelated update:
Well, I plugged my Mandrake drive back in. Now I have a choice between Windows XP, Mandrake 10 or SuSE 9.1. I haven't used XP in 6 months so time will tell which of the latter two distro's I end up booting up to in the future. I wasn't able to boot up to SuSE initially because I was using a Promise raid IDE port. Linux can see it but the BIOS doesn't like that. So now that port contains my Mandrake /home partition.

Differences I've notices so far between SuSE 9.1 and Mandrake 10:

The SuSE setup was able to setup twin monitors. However, I couldn't get the LCD monitor to be the first monitor, and being able to go back to one monitor was a chore. ( Plus I need to clean up my computer desk to make room for two monitors.)

I prefer the way Mandrake handles new users, and putting non-standard mounts under the /mnt directory.

I like the SuSE method of altering files in /etc/sysconfig and using a makefile type setup ( SuSEconfig) to propagate the changes were they need to go.

SuSE has always had the best manuals in my opinion.

I had gone back to Mandrake simply because it would install when I bought my last computer. SuSE still has one of the IDE drives erring out up until the point where my manually selected IDE DMA mode is applied ( I wasted money previously on SuSE and RedHat).

Mandrake's hot-plug system works for CD's, USB drives, and Key drives.
SuSE didn't set up my USB Key drive properly. It thinks it's a CD and isn't able to mount it.
K3B doesn't see any CD drives at all.

SuSE 9.1 includes 3 DVD's for installing to an AMD Athlon 64 system. If I get generous with myself around Christmas, I'll be prepared!

SuSU's Y.O.U. system downloads patches while Mandrake's urpmi downloads the full RPMs. If I were using a modem, patches would be a large advantage.

Well, I'll get to these tweaks later. I can manually mount a USB drive no problem.
