It supersedes BSD + <tt>init</tt> and the NetBSD <tt>rc.d</tt> system, drawing + inspiration from Solaris SMF for named milestones, + daemontools-encore for service control/status mechanisms, UCSPI, + and IBM AIX for separated service and system management. It + comprises a range of compatibility mechanisms, including shims for + familiar commands from other systems, and an automatic import + mechanism that takes existing configuration data from + <tt>/etc/fstab</tt>, <tt>/etc/rc.conf{,.local}</tt>, + <tt>/etc/ttys</tt>, and elsewhere, applying them to its native + service definitions and creating additional native services. It + is portable (including to Linux) and composable, it provides a + migration path from the world of systemd Linux, it does not + require new kernel APIs. It provides clean service environments, + orderings and dependencies between services, parallelized startup + and shutdown (including fsck), strictly size-capped and + autorotated logging, the service manager as a + "subreaper", and uses kevent(2) for event-driven + parallelism.</p> + + <p>The past few months have seen a growth in the import + mechanism, with full import of <tt>/etc/fstab</tt> and + <tt>/etc/ttys</tt> available in version 1.18 in July, and importing + PC-BSD Warden and &os; 9 jails, and full import of <tt>gbde</tt> and + <tt>geli</tt> mount/unmount mechanisms in version 1.21 in October. + It has also gained the ability to automatically re-generate + <tt>host.conf</tt> and <tt>sysctl.conf</tt> whenever their source + files change.</p> + + <p>Other developments in the past few months include fully + independent shutdown support, no longer relying upon an externally + provided shutdown command from another toolset, and a full suite of + binary packages. As of version 1.20, it became possible to + have a fully-nosh-managed system, on both &os; and Linux, using just + precompiled binary packages.</p> + + <p>The biggest task remaining is one that was set a while ago: + the creation of enough native service bundles and ancillary + utilities to entirely supplant the <tt>rc.d</tt> system. A + lot of this has been achieved, with the original target list of + 157 items now down to just 39 remaining. These are the tricky + ones, of course, where help is most needed. + </p> + </body> + + <help> + <task> + <p>There are still a few rc scripts left that should be easy + to convert, such as <tt>/etc/rc.d/gptboot</tt> and + <tt>/etc/rc.d/growfs</tt> as oneshot services, + <tt>/etc/rc.d/routing</tt>, and <tt>/etc/rc.d/kldxref</tt>.</p> + </task> + + <task> + <p>&os;'s <tt>/etc/rc.d/bluetooth</tt> is over 360 lines long. + In 2011, Iain Hibbert wrote a "simpler" <tt>bluetooth</tt> for + NetBSD. This can perhaps be used as a simpler basis for a nosh + translation.</p> + </task> + + <task> + <p>Add kernel support for passing a <tt>-b</tt> option to + pid 1, and support for a boot_bare variable in the loader, to + allow "emergency" (where even no shell dotfiles are + loaded) and "rescue" mode bootstraps, akin to Linux. + (History: The <tt>-b</tt> mechanism and idea date back to + version 2.57d of Miquel van Smoorenburg's System 5 init clone, + dated 1995-12-03, and was already known as "emergency boot" by + 1997.)</p> + </task> + + <task> + <p>Add support to &os;'s fsck(8) for outputting + machine-readable progress reports to a designated file descriptor, + so that nosh can provide progress bars for multiple fscks running + in parallel. nosh already provides this functionality on Linux, + where fsck(8) does provide machine-readable output.</p> + </task> + + <task> + <p>Identify when the configuration import system needs to be + triggered, such as when <tt>bsdconfig</tt> alters configuration + files, and create the necessary hooks to import external + configuration changes into nosh.</p> + </task> + + <task> + <p>Investigate how &os;/PC-BSD could be improved by taking + advantage of some available nosh package mechanisms.</p> + </task> + </help> + </project> + </report>
