Re: Thoughts on roaming laptop setup for Debian Edu

With NFS, such setup would cause NFS hangs for a lot of processes
(anyone doing the equivalent of ls -l /), so we choose
/skole/host/home0/username for Debian Edu.

Great.  I'm unable to reach the server now.  Not sure what is wrong.

Sound very useful, and perhaps a better idea than our current autofs
based implementation.

Right.  I've asked for pam_mkhomedir to get pam-auth-update
configuration in Squeeze (#485282), and home it will be available in
time.  If it is, setting up such configuration would consist of
installing a libpam-mkhomedir package. :)

Thanks.  I am aware of two solutions for this, one using nscd and one using pam-updatedb.

Sound like wicd might be a good solution for roaming workstations.  It
should be possible to configure network-manager to configure network
before a user log in (ie at boot), but I have not been able to get it

In KDE, network-maanager is integrated with kwallet, and ask for
wallet access even for non-encrypted wireless networks. :)

Yeah.  We have a framework in place, but no-one documented how to use
it and I doubt anyone is using our framework for distributed
cfengine. :)

Happy hacking,
