This is sort of a continuation of the thread started with the post "Recommendation for Virtual Machine and Instructions to set it up?"
(https://lists.debian.org/debian-user/2018/12/msg00144.html) Aside: the programmer has been able to send me a binary which does work on my Jessie system, but, never-the-less, I plan to start experimenting with either a chroot or VM environment to run either sid or a recent Ubuntu release so that I can compile / build the binary myself. The machine I want to do this on does not have any unallocated partitions / disk space. There are two partitions, currently used for other purposes, that I could free up to use for the chroot (or, later, VM) by moving files around. The Question: One of the partitions I could free up is 16 GB, the other is 54 GB -- I'd rather free up and use the smaller one, but I'm wondering if that will be big enough?
