Hi,
I have a Linux eval board (running ubuntu) that boots off a 2G eMMC device. Everything is currently mounted on that device, so as I add packages with apt-get, they chew up this space. I've got about 400M free, and I know I'll need more because of the packages I'll be installing. I'm sure there are things I could remove to free up some space; but I'd like to avoid that if possible.
The board also has a uSD card, so I can easily add to the 2G, but obviously that'll be on a different device/partition.

Can I tell apt-get to install to the new disk?
Is this a good use of OverlayFS?
Other suggestions?
Thanks

I don't know if the overlay FS will work for you.

How about putting as much "data" or user home stuff onto that SD card and leaving the internal MMC with just the installed packages?

There's essentially nothing under /home at this point.
I have to dig a bit to see what is actually taking up 1.5G of space.
This is how it is shipped.
I don't know a lot about overlay FS, but why do you say it may not work?

I said "I don't know" because I "have no idea", I don't know details about the overlay file system at all.

Yeah, use the df and the du -s commands to determine where all the space is being used up.

My experiences with embedded board, and this is a guess, but a good one, is that the space you have is just about the limit you do have. Might be better to run a more compact distribution.

Is that an old Beagle? They have newer ones with 4G of eMMC.

as far as i understand the persistent live overlay for fedora continually gets bigger and bigger. even after deleting files the overlay file is unable to reclaim that space. i usually create another live-usb after a few months.
