Does your mileage vary that > much, or am I simply missing the point? Hi Urban, I failed to make my point. Let me try again... The one and only point in replacing an easily comprehensible, self-contained and statically linked piece of code by some script is for the purposes of demonstration and propaganda. Nobody in their right mind would permanently use a shellscript to PID1 a machine used to do actual work. Felker's PID1, and even more so Suckless Init, are system level C that aren't as comprehensible as /bin/sh or /bin/csh would be. Especially if Edward would comment liberally. Right now, Felker's PID1 is the acknowledged "Hello World" PID1. But as I remember you have to add an #include to get it to work with mainstream Linuxes, you have to get it to compile, and it's just not as understandable to non-C programmers. Hackers who might not know C are more able to put their own commands into the shellscript and see the result. And then there's the propaganda value. Over and over and over again, Lennart and the Redhats have told us how complex, do not touch, no user serviceable parts inside init systems are. And now we find that Edward Bartolo has used a couple shellscripts and some commands from runit to init a computer. It's priceless. Edward Bartolo > Lennart Poettering The preceding angle bracket means "greater than" Here's an article I wrote with a similar flavor: http://troubleshooters.com/linux/init/manjaro_experiments.htm#is_that_all_there_is So Urban, once again, the reasons for a shellscript PID1 are: * Learning * Demonstration and teaching * Propaganda For real systems doing real work, use a compiled PID1.
