netenv 0.94.3-30 (s390x binary) in ubuntu yakkety

 Netenv lets you choose your network environment (and other things)
 upon boot, which is useful for notebook computers. The difference to
 similar packages is that it doesn't try to autodetect your
 environment, but expects your input. You can, however, specify a
 default or pass it a parameter from the boot prompt to allow for
 unattended boot. You can also use it to switch between environments
 without rebooting.
 .
 It will work with PCMCIA or builtin network cards.
