Our school will finally be moving on to Ubuntu 14.04 LTS from XP (most probably). There will be a pilot run on ~40 PCs with same hardware. So what would be the best (and least time consuming) way to install Ubuntu to these computers? We want a fully configured Ubuntu which should be identical on each computer.
The present steps we are considering:
Use Clonezilla: Install Ubuntu on one hard disk, install apps, configure it and then use Clonezilla to clone the hard disks.
Concerns: Disk UUID's, their behaviour on same network (same hostnames).
Use Remastersys: Make a fresh installation, install apps, configure it and use Remastersys to create a full-backup type installation ISO and then install it on all PCs to get fully configured PCs
Concerns: Will it really work (in theory it should), time consuming, too many steps involved.
All PCs will be identical, even their usernames so perms are not an issue. Please suggest some better way to do this.
Note: Not all PCs are on network so network installation is not an option.
Please help as it is a make it or break it situation for the deployment of Ubuntu.
