wouldn`t it be useful to add a hint to kernel-parameters.txt ?


for now it just reads:

        init=           [KNL]
                        Format: <full_path>
                        Run specified binary instead of /sbin/init as init
                        process.

so, if there is no hint about that specialty (i.e. passing params to init, using for chroot etc..), no user will ever now.....
