It can surely cut down the RAM footprint and boot-up times of my node but I'd still need to have a *copy* of the VM image/rootfs for each of the nodes on the disk (each disk copy being several 100 MBs). The reason for this *copy* is: I'm using ext4fs which does not support efficient cloning of LxC disk images. Reformatting my existing ext4fs to use, say, zfs or btrfs (that both support cloning), would be very disruptive/painful! > > So, staying within ext4fs, what are my options for having disk-, RAM-, and CPU-friendly nodes for learning TCP/IP network and system administration, and some security topics as well? > > Thanks in advance, > /HS Buy a bunch of Raspberry Pi's and a switch. -- -TV
