I have been using the Ubuntu Live USB since I made it and I must say I am pretty impressed. It works and it works really well.
- All settings remain persistent.
- Apt packages installed are all persistent.
- Compiz settings manager and Emerald can be installed and persist.
- AptOnCD can still be used.
- Even Samba works
As of now I have found just one thing that does not work. The fstab entries do not persist. So you are going to have to manually mount the local disks each time. But that isn’t a problem. Actually I find it a boon considering that the local disks on each PC will be different. Haven’t tried using the same USB on another PC, but I am guessing it wont be much of a problem. Anyways, it still is a great thing as a rescue system and even to use it regularly as an OS, which I have been doing ever since I got it to work.
Check out a few screen-shots below.
