[luau] Mixing Linux and Windows

[Yuser]

I have two Debian systems [1] at the house for my kids.  I am trying to 
make them as Windows like as possible for my kids.  For my actual Windows 
machines, they do domain logins and have roaming profiles with network 
directories and storage from a third linux machine running Samba.  That 
works great had has been for years, but what is the best way to get 
similar functionality with the Debian machines?  
I mounted the non user specific shares via smbfs in fstab and created 
links to them in thier home directories, this works fine because they are 
read-only and permissions are not an issue.  How can I mount or link their 
user specific Windows home directories from Samba automatically like 
\\server\homes and maintain the proper permissions?  Although possible, I 
could NFS mount the entire /home partition as the /home on the debian 
systems as I already have a common Linux home that I share between other 
Linux machines (all users and groups id's match across all Linux machines) 
but since they do not actually use these machine directly, I never had a 
need to integrate the Samba shares into them.  Is their a potential for 
NFS and Samba clashing on open files and file locking bewtween the Linux 
machines on NFS and the Windows machines on SMB?.  I don't know.  My goal 
here are things like Bookmarks and the "My Documents" folders.  It would 
nice to have user specific common directories accessible from all the 
machines where they can put their files to have available anywhere.

My Debian machines they use came from Knoppix, the live CD distro, I liked 
what they offered and converted them to hardrive format from the live cd 
(Knoppix includes scripts for this).  They work great with the exception 
of Windows games but they do 95% of what they need and they like them.  I 
like them because they are no longer getting infested with Spyware and IE 
hijacking software that my kids always seem to download.  They are only 
P200's/256MB ram but they still work fine and about the same speed as when 
Win98 was on them.  I was already using IMAP in the house so email 
conversion is not an issue.  The only standing issues are the CUPS 
printing to my Intel Netport does nothing and the above mention of dealing 
with the SMB shares.  If you want to try Linux, I highly suggest the 
newest live CD Knoppix release from www.knoppix.net.
