Holidays come early for distro builders with two init systems to choose from
Everyone's favorite Linux component has hit a milestone, while a fresh contender comes of age – with a touch of Lisp.. They're very different ways of doing the same basic task, and we're happy to see more options in this particularly controversial role.To recap that fun little feature, if you run the systemd command to clear up temporary files, and you don't get it exactly right, it totally wipes the entire tree of user home directories.
If the dollar sign is used, the file becomes subject to removal when systemd-tmpfiles is invoked with the –purge switch. Lines without this character are unaffected by that switch.sub-command will remove. It's a small enough change, but it means that if that config file doesn't tell it to, the commandnow will not delete everything in every folder created since the first user was added. So that's good.
The other changes are mostly far underneath the covers, so to speak, and will likely be invisible to anyone who isn't maintaining a Linux distribution. The tooling around theversion 1 and System V service scripts inch close to being deprecated, it now understands volume button presses on mobile phones – showing how mainstream Linux is moving into more pockets – and it's offloaded some old keyboard handling code to X.org.
Scheme is a smaller, simpler version of Lisp, originally designed for educational use. As we quoted when talking about the, there are three main branches of the Lisp family tree: the stripped-down Scheme; Emacs Lisp, which is the extension language of the 800 lb gorilla of text editors, Emacs; and the heavily standardized Common Lisp. AsCommon Lisp is Howl's Moving Castle.
