The complete configuration can be saved by giving lrcfg -> b -> l -> q -> q
For the sake of ease of use, I have defined a command alias in my profile to save the configuration as follows:
alias savecfg=?echo ?e b\nc\nl\nq\nq\n|lrcfg?
This simulates keyboard input of lrcfg -> b -> c -> l -> q -> q
Reboot.
