If you don't need X, you can reclaim space by removing x11-common. I like to run on the eMMC myself, mainly because I keep loosing the micro SD cards :)
I recommend looking through the installed packages and removing what you don't need. There is a great Debian wiki page on how to do this: https://wiki.debian.org/ListInstalledPackages . This command also appears to work as well: dpkg-query -Wf '${Installed-Size}\t${Package}\n' | sort -n Lastly, I've seen recommendations to install the wajig package to determine the size of all packages installed. However, it takes about 14.4 MB: The following NEW packages will be installed: python3 python3-apt python3-minimal python3.2 python3.2-minimal wajig 0 upgraded, 6 newly installed, 0 to remove and 60 not upgraded. Need to get 4,514 kB of archives. After this operation, 14.4 MB of additional disk space will be used. Do you want to continue [Y/n]? n Ironically, you may not have enough space to install this package :p Josh -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
