- Deploy shopfloor-setup with rsync instead of the copy module: the ~4 GB tree took about 4 minutes on every re-run because copy checksums each file. rsync transfers only changes; changed only when it did. - iPXE drops a trailing space, so 'Machine number:' ran into the typed digits. The space now comes from a hex 20 setting. - tests/vm: pxetest-xp is a permanent client (SeaBIOS, qemu32 32-bit CPU, rtl8139, 1 GiB, IDE disk) for the i686 Clonezilla path; start.sh xp. Only one client may run at a time across all three.
