switch to a new operating system configuration
.TP
roll\-back
switch to the previous operating system configuration
.TP
describe
describe the current system
.IP
list\-generations list the system generations
switch\-generation switch to an existing operating system configuration
delete\-generations delete old system generations
build            build the operating system without installing anything
container        build a container that shares the host's store
vm               build a virtual machine image that shares the host's store
vm\-image         build a freestanding virtual machine image
disk\-image       build a disk image, suitable for a USB stick
docker\-image     build a Docker image
init             initialize a root file system to run GNU
