I'm trying to figure out what are the criteria behind the installation in object, to see how I can properly use it, improve something or possibly replace it with something installed from scratch to better suit my personal needs. Possible questions follows.
- What are the benefits of an Ubuntu installed just in one single primary partition, that is /dev/sda3?
- Why the related filesystem is ext3, though Maverick is shipped with a kernel recent enough to handle ext4?
- What's the purpose of the first primary partition, that is /dev/sda1? I noticed it's FAT and when the system is up it is not mounted...
- How is the bootstrap supposed to work? While upgrading packages a dialog box appeared concerning possible destinations for grub, but, though I was pretty sure MBR was a suitable place, I ended up choosing both sda and sda3: if I'm not wrong I was not allowed to go on unless I checked them both... Anyway I was not happy to proceed without understanding what I was actually changing, I didn't know what there was initially in the MBR and what there was in the partition boot sector of sda3...
- What can I do in order to perform kind of a "blind" system recovery? I mean, I can install Ubuntu from scratch, but what if I wanted to reproduce the exact initial conditions at the very first boot of the machine? I thought a dump of sda or separate dumps of sda1 and sda3 would be very useful, unfortunately I didn't launch my "dd" timely to get those dumps on my own. Would you ever make that kind of dumps available?
Many thanks in advance
