Backing up installed packages.
I keep a list of installed packages around so I can easily populate a new disk
(or repopulate a mashed-up disk) by doing something along the lines of
$ apt-get install $(cat installed-packages-list)
I use a daily cron job along the lines of
ls /var/cache/apt/archives | sed 's/\([^_]*\)_.*/\1/' | sort | uniq
to maintain an installed-packages list that looks like this:
$ cat installed-packages-list
aalib1
base-files
bash
bittorrent
bzip2
cdrecord
[ and so on ]
I would be interested in hearing opinions and suggestions about a general
approach to backing-up and reconstituting package archives, as well as opinions
and suggestions about the particular approach I've outlined above.
