oops "boot into backup cycle" is my method of installing new systems. I create them in a chroot/lxc on a NFS server, and boot the real system or laptop by PXE, rsync it on the disk and make it bootable. The real system will also rsync itself to this master, and the master is doing incremental backup. So every system has a backup before it even exists on its own disk, and installation is just a normal restore of a backup. Also on Chromebook, specs tells some funny CPU, and only 2+16GB of SSD. Thats much lower than an old eeepc1000. Especially as it likely ships some funny crippleware, and not a minimal Debian, Arch or Gentoo.
