Not sure what you mean, Ianni.
To keep up to date, all you need to do periodically is:
- Code: Select all
equo update
to update the Entropy database on your PC (the database is essentially the list of available packages and their versions), and:
- Code: Select all
equo upgrade --ask
to update everything to the latest release (add the "--ask" in case there is a package you do not want to upgrade, or to review easily the packages that will be upgraded).
You should also keep the Portage database on your PC up to date periodically too:
- Code: Select all
emerge --sync && layman -S
That's it, basically. So no need to download ISOs for LiveDVDs.
Regarding repositories, 'branches' and the more detailed aspects, see the SL Wiki articles on Entropy. The one to start reading is:
