Smart way to reinstall Linux software after crash

Filed under: Uncategorized — ubuntudemon @ 12:45 pm

A real easy way to backup a list of installed software. This will also work on Ubuntu as it is based on Debian.

A tip :

When installing Ubuntu make / and /home seperate partitions. If you ever need to reinstall you won’t lose your personal documents and user preferences stored in /home. Although you should make backups of important data anyway in case of a mistake or bad luck such as a power outage.



  1. You can also save (and restore) the list of installed packages from synaptic, there is an option in the file menu.

  2. Ideally, the installers really should partition like this by default, given enough minimum space allocated by user. And it should then also try to be aware of this kind of existing install and offer to “repair”.

  3. ahh but the _real_ question is :
    in what order to do place the partitions?
    in theory I guess / should be 1st then /home then /swap (for performance purposes)

  4. AFAIK the ordering of the partitions doesn’t make a big difference.

    On a clean harddrive I would also go for / , /home , swap (not mounted).

    5-10 GB for / (10 GB is nice for power users and people who install a lot of stuff like big games) If you have disk-space-problems and you don’t plan on installing much software at all (except for codecs and stuff) then 3 GB would even suffice.

    /home the rest of the space

    500-1000 mb for SWAP. roughly 3 times the size of your memory with a minimum of 500 mb swap and a maximum of 1000 mb swap. This is more than enough for normal users. If you do a lot of video editting or other memory-hungry stuff then you might need more swap then this. It can’t hurt to have a too big swap partition but you don’t want to waste too much space.
