pid1: initial "run as PID 1" feature This one has been inspired by these guys: http://www.informatimago.com/linux/emacs-on-user-mode-linux.html https://raymii.org/s/blog/Vim_as_PID_1_Boot_to_Vim.html It's aimed at building images running their main userspace piece instead of ramdisk's init, that means PID=1, UID=0. Mostly fun of course but it suddenly became interesting with kernel IP autoconfiguration and e.g. elinks running this way (NB: requires patched make-initrd 0.8.8 at the moment to get resolver configured). And startup times are way better than sysvinit and systemd combined! 2014-09-18 22:33:19 +04:00			`label pid1`
