I won't add any bloat here for a boot-time menu for HOME/CAR.
But in v178 I have added ';@AC' and ';@DC' as valid tags (very cheap, codewise).
And also new in v178: by default, kftpd/khttpd will not run in DC/Car mode -- saves us a few pages of memory for added buffering in the bumpy car environment. But if you want them anyway, use this option in config.ini:
[hijack]
dc_servers=1
v178 will be released in a minute or less from now.
