Hi all,
I was wondering, there are several ways to separate the machine where storage for home directories are provided from the place where it is needed. This is needed in case you have multiple (virtual) desktop machines, where a number of people could log in.
Most obvious techniques are nfs and smb, and perhaps if you can enforce that no one is ever logged in twice, one might use raw block devices.
Point that kept me awake, is the scalability: it might very well work for ten or hundred users, but what when confronted with 1000, 10.000 or more users?
At the desktop-side, i presume you have to limit the amount of simultaneously logged in users to 100-200 (depending on the amount of mem in a server). And with pam, you can mount the user dir when needed.
automount works very well too when working with individual mounts.
Clearly, from the point of view of load and availablity single exporting servers should be ruled out. But how many exports is feasable?
And how many nfs/smb-services can you have on a single server?
Depends on the server :-)

And i forgot to mention, I start with a very thin-client (only nx/x2go/thinlinc) and they get to choose between an virtualised remote XP/W7 desktop or an LXDE desktop. And either desktop must be provided with home-storage.
Ooo, there's a gotcha there concerning file locking. We've never got nfs/cifs locking to work. We had to go cifs only if we wanted file locking to just work between LXDE/xp/w7. This really is a killer with m$ office and Libreoffice docs. The good news is that cifs on openSUSE is great these days, Kerberos, autofs; the works.
