Playing with a shell script (or a C code, for that matter), and making something that calls rc might be somehow istructive and fun, but it should be clear that this is not "creating a simple OS initialiser" which can be used outside of a sandbox. Before coding an init system, I would probably start with coding a shell, with basic command execution, environment management, background processes, a few builtins, I/O redirection, pipes, and proper signal management. That is a really instructive and fun exercise, IMHO, but I admit that the definition of "instructive" and "fun" is quite subjective :) My2Cents KatolaZ -- [ ~.,_ Enzo Nicosia aka KatolaZ - GLUGCT -- Freaknet Medialab ] [ "+. katolaz [at] freaknet.org --- katolaz [at] yahoo.it ] [ @) http://kalos.mine.nu --- Devuan GNU + Linux User ] [ @@) http://maths.qmul.ac.uk/~vnicosia -- GPG: 0B5F062F ] [ (@@@) Twitter: @KatolaZ - skype: katolaz -- github: KatolaZ ] _______________________________________________ Dng mailing list Dng@lists.dyne.org https://mailinglists.dyne.org/cgi-bin/mailman/listinfo/dng
