Recovery after removing avahi deamon

I was until a few hours ago the happy user of a Fedora core 5 (on opitplex gx620) system that had taken about a week to get fully working with a lot of custom compiled software installed. Thanks to the excellent introduction to the livna drivers in this forum the ATI card worked excellent too.

Today the sysadmin wanted to copy the user accounts onto the system and did this simply by copying /etc/shadow and /etc/groups and etc/passw to the new machine.
Is this a good approach?
It seemed that some deamons (HAL and Avahi) were dependent on some existing user ID's and would then not start.
I naively used yum remove and subsequently reinstalled avahi, but for some reason the system now will not start up now. It freezes just before the login screen usually appears.
Could someone please give me a hint as to where to look for the problem as I would really hate to reinstall everything.
HAL and AVAHI still fail by the way but i am not sure that they can be the real cause for the missing start.

No, copying the files is not a good idea, ever. The system accounts (uid/gid less than 500) should not be altered. User accounts can be manually edited in, if you are careful to keep the files consistent, and manually created the home directories.

You will need to restore the files that were overwritten. I assume, since you have a sysadmin, that backups were taken before any manual modifications to system files. If not, it's time to get a new sysadmin.

Thanks, yes good practice would have been to backup the old user accounts.. I could not get X to start even with avahi re-installed so I have now re-installed as it seemed the fastest option.
