I am running beaglebone black on ubuntu installed on sd card. i am learning to program the device in trial and error method by installing various packages (just like CERN guys study sub atomic particles by hitting them together in various angles and studying their trajectories). So can i initialize a git repository at root directory and ignore volatile directories like /sys and /proc? Or watching what system directories is sufficient to successfully time track entire OS? Are there any similar snapshoting tools? Other than git, what repository system is best to time track binary files?
How to change filesystem to ZFS? During ubuntu installation am i provided with ZFS filesytem option in addition to extX, FAT, NTFS etc. filesystems, I never noticed?
--EDIT--
What is list of non-volatile and important(unlike /tmp) directories in /?
first, I don't think that git is a good solution for binary files.
maybe is better to use virtual machine in virtualbox where you can create snapshots (as many as you need) of entire system
to change filesystem (how I know) you need to format the partition (don't know about zfs, but you can use Gparted, maybe he can, gparted is an advanced partition manager, user friendly)
