Wow, just yesterday I was wanting a reloadable inittab.  I'd support
inclusion, with or without a possible
CONFIG_FEATURE_INITTAB_RELOADABLE-like variable.

In terms of practical applications, I'm building a diskless server
which optionally can act as a terminal server, and if my Rocketport
multiserial card is present, I want to add a bunch of gettys to
inittab and get those served.  Currently, my workaround is to do
hardware detection before my pivot_root, append the needed lines to
the tmpfs /ramdisk/etc/inittab file, and let the new inittab get read
after the exec /sbin/init.
