My root partition is getting cramped (slightly less than a gig of free space remaining). So I'm thinking about moving all the *.deb's in /var/cache/apt/archives to another folder in another partition (/media/backup/apt) and tell apt/synaptic to permanently use it as cache folder. I know how to move the files but I still can't figure out how to make apt/synaptic always refer to this folder to check for and and store downloaded packages. Can someone please kindly tell me how to accomplish this?
Thank you in advance.
