[K12OSN] Moving Home files to a new server

[Carl Keil]

Hi Folks,

So, the big disaster happened.  My K12LTSP hard drive died.  I've got 
everything backed up (thank you BackupPC), so I thought I was golden, 
but I'm having a weird problem.

When I restore files from backup they are showing up "read only" in 
people's directories.  When I do a "ls -la /home/username" it is showing 
that the files are owned by other users and other groups.  A "chown -R 
username:groupname /home/username" doesn't solve the problem. 

I tried copying over all the 500+ /etc/passwd and /etc/shadow info from 
the most recent backup but after that I couldn't even log in as 
different users.  Any suggestions for what I should do?  I'd really like 
to just set up new user accounts for everyone and then just copy over 
selected files from backup for each user.  This is a family installation 
of K12LTSP, so there are only about 10 user accounts.  I used "useradd" 
on the new server to create everyone's account and I don't think I did 
them in the same order as the original server.  Should I delete everyone 
and re-add them in the exact same order?  I could do that based on 
/etc/passwd from the backup?

Thanks a lot,
