A meta-repository which includes all repositories would be great. Then a repository-manager could manage repositories.
So i could select all repositories i like to be setup in the application manager.
i keep a copy of that list on my rs-mmc card along with osso-xterm and becomeroot packages so that when i rebuild the 770, as i have for the 3rd time now, i can simply install the two packages and copy the file on the card to /etc/apt/.
It would be nice if xterm were part of the standard firmware - I've flashed my 770 so often now that I've gotten most of the restoration process setup in a shell script which copies in a full sources.list, runs apt-get update, pulls down the apps I need, and restores any non-standard apps/data (including .ssh, NFS and GNU tar) from a tar ball stored on MMC. Then reboot and job done.
The longest/most tedious part of it all is adding the single repository needed to download xterm, and given how useful xterm is on the 770 I don't know why Nokia don't install it as standard and make it available to anyone running their device in R&D mode. I can understand it might be a bit "scary" for anyone who isn't running in R&D mode - arguably these are "regular" or "non-power" users but not always in which case could Nokia add a new switch (--enable-xterm) to the flasher utility which would render xterm available on the newly flashed device?
