Is PCL the only rolling distro? Can others be updated in bits and pieces?
You should not update "in bits and pieces." A full update is always recommended.
You only update the 'bits and pieces' you have installed that have changed. I think that's what he was saying. Full install not needed.
Yes, that is correct!
A full update does indeed only apply changes to what is installed.
In a traditional environment, only the applications and their libraries and such are considered "installed".
A rolling release is different in that one of the things that is considered "installed" IS the operating system.
This means that when you do a "full update" if changes have been made to the operating system, they are updated as you go, on the fly.
Other distros save all these changes up and then do a "Release" of the new changes. That release is in the form of a brand new .ISO that then requires the user to do a full new install from scratch to get the changes implemented.
Our "Releases" on the other hand, are simply an ISO that contains all the changes that have been made since the last "Release".
Changes that should already be in place on an install with regular "Full" updates.
This simply saves the user time (for the most part) from having to download a million updates from an iso that is more than a year or so old.
TMI? Perhaps, but not worthless.
