darknedgy.net: uselessd :: information system – use less
Support for compilation under musl and uClibc. This has meant eradicating plenty of GNUisms, including ones that spread out as deeply as requiring specific printf(3) semantics. No journald. Consequently, this also means no libqrencode and libmicrohttpd integration, nor hooking coredumps to the journal. The default log target for auxiliaries is now LOG_TARGET_KMSG_OR_SYSLOG. The main case against binary logs is their corruptibility. This happens more often than you’d think, due to not having any transaction consistency, as an RDBMS would. The advice of the systemd developers on handling this? Ignore it. Otherwise, the main legitimate case for binary logs (but actually journald in particular) is Forward Secure Sealing. This is no longer a dealbreaker, since rsyslog supports log signing through GuardTime since 3.7.9 now. You can also use a combination of OpenSSL or the NSS signtool plus logrotate jobs to verify log authenticity, though this is more intricate. Secondary concerns includ
systemd is viral by its very nature. Its scope in functionality and creeping in as a dependency to lots of packages means that distro maintainers will have to necessitate a conversion, or suffer a drift. As an example, the GNOME environment has adopted systemd as a hard dependency since 3.8 for various utilities, including gdm, gnome-shell and gnome-extra-apps7. This means GNOME versions >=3.8 are incompatible with non-Linux systems, and due to GNOME’s popularity, it will help tilt a lot of maintainers to add systemd. The rapid rise in adoption by distros such as Debian, Arch Linux, Ubuntu, Fedora, openSUSE and others shows that many are jumping onto the bandwagon, with or without justification. It’s also worth noting that systemd will refuse to start as a user instance, unless the system boots with it as well – blatant coercion8.
With the RYNO, you’re not limited to the street or the bike lane. It’s a transitional vehicle – it goes most places where a person can walk or ride a bike. In an effort to get people out of their cars, cities are trending to allow personal mobility products to mix with pedestrian traffic. See our Regulatory Page for more information on where you can ride.”
