-What is the apt-get or update manager procedure for updating?
-Can it be configured to only download packages NOT already installed?
-Can packages be saved for re-installation?
I've been testing and learning about Ubuntu since my first Feisty Fox setup nearly two years ago. My primary goal is to have a computer that isn't web-dependent - one that can work and be managed even if the whole web dies or decides it hates me.
Finally, in August, I set up dial-up service to try to go a but further than I could with only the CD (mailed snail-mail from Canonical - thanks!) and research at the library's terminals.
I'm on my third build of Ubuntu 8.04 Hardy. Not yet having discovered a way to do a full, restorable backup (Drive Image won't handle Linux partitions at all), I just started over when things got messy. I do like to experiment.
Unfortunately, dial-up download is quite slow, and update manager seems to want to do its thing in one big go. I have to download larger (over a meg or so) updates one at a time and let them install, as there's no provision for interrupt/resume. And as far as I can tell, it doesn't check to see if a particular update has already been installed BEFORE downloading it again!
My last installation spent 23 hours tying up my phone, but got caught up. Then I ran update manager again, and it wanted to download it ALL over again! Synaptic seems to use the same procedure. SO...
1. Is there any way to download ONLY things one hasn't downloaded before?
2. Is there any way to save and then re-install previously-downloaded updates for future rebuilds?
I'm already worried I won't be able to re-download Firefox 3.0.13 when they want to force us to 3.5x and I'm not comfortable with it yet.
BONUS QUESTION: is there anything that provides Drive-Image capability to ext3 partitions? That is, the ability to save a partition so that it can be restored to a completely blank drive. Drive Image does it by being a DOS floppy-based program, and I like that - you can restore even if the target machine has no operating system working at all.
Thanks for listening and, to those who take the time, trying to help.
