How to reinstall *everything*?

I suggest you download my backup.pl script:
Then become root:
then create a file called .backuprc with:
# # uncommend below what you want to customize
# # BACKUPDIR must be specify for the script to work properly.
# # unless you want to put the files in /home/backup
# ## bzip2 or gzip? or don't define if no compression is needed
# ## prefix to name of the file
# ## Users must define this
# ##perl compatible + shell regex
SYSTEM=/etc /var/mail /var/spool /var/lib/iptables /root
This script just backup all your directories defined in SYSTEM and all
your users' homes with id's higher than 1000 (regular users). All the
files will be placed in
They will have names like: my-desktop-system-`date -I`.tar.gz,
my-desktop-other-`date -I`.tar.gz, my-desktop-`list of users`-`date
And finally there will be a file called: my-desktop-selections.txt.
Which is created with: dpkg --get-selections \* >
Once that's done, you can reformat your disk (assuming you can copy
the tar files from /home to a safe disk, say a DVD).
When you are done, re-install ubuntu using a Dapper disk. Then get the
my-desktop-selections.txt file and re-install the stuff you had before
cat my-desktop-selections.txt | dpkg --set-selections
dselect update && dselect install
After that, if you ever need a configuration from your old system, you
have a tar file that you can open by double-clicking on it, and copy
the file to your /etc folder.
Generally, unless you are on a server, you don't need these files ;-).
ubuntu does the right thing for you at installation.
Hope that helps somebody out there...
