The && and || operators should be left-associative, since that is how
they are treated in most other languages (including C and Unix
shell). For example, in the command:
dhcp net0 && goto dhcp_ok || echo No DHCP on net0
if the "dhcp net0" fails then the "echo" should be executed.
After an "exit" or a successful "goto", further commands on the same
line should never be executed. For example:
goto somewhere && echo This should never be printed
exit 0 && echo This should never be printed
exit 1 && echo This should never be printed
An "exit" should cause the current shell or script to terminate and
return the specified exit status to its caller. For example:
chain test.ipxe && echo Success || echo Failure
[in test.ipxe]
#!ipxe
exit 0
should echo "Success".
