This one is quick and closely related to what I discussed in the previous installment:
There's now a new verb "dlopen-metadata" in systemd-analyze that extracts the dlopen() metadata from an ELF file and displays it in tabular form.
It's that time again! The systemd v259 release is coming closer. Let's restart the "what's new" series of posts for this iteration! Hence:

For many usecases it's quite useful if local services can register additional hostnames for local resolution. For example, container and VMMs might want to register the IPs of locally running containers or VMs via a hostname, so that you can…

For this one I am simply going to top-post @daandemeyer's story about run0's new --empower switch, which gives your process capability + polkit privileges, without changing your user ID. Very powerful stuff.

If you have systemd v259 on your system, and you run "ldd /usr/lib/systemd/systemd" (i.e. query the shared library deps of the systemd service manager binary), then you get the following output:

systemd-modules-load.sevice is an early-boot service that loads a list of kernel modules into the kernel that is configured via /etc/modules-load.d/ (and similar dirs under /usr/ + /run/ as usual). It's half a legacy feature, because nowadays kernel modules are generally auto-loaded based on "modalias" information they expose, which binds them to certain hardware vendor/product …

Here's a short one: systemd v259 will compile fine with musl libc, out of the box.
Sounds great? Well, it's not as great as it might sound to some. musl has quite some limitations compared to glibc: the primary one is that there's no Name Service Switch (NSS) support. That's the subsystem that allows systemd to make domain names, user names, groups names resolvable via…

systemd-repart is systemd's dynamic, elastic image generation and repartitioning tool. It can either run "online" during early boot to create/encrypt root file systems or other partitions on the running system, or it can run "offline" to prepare images that can later be booted.
With systemd v259 it gained one new trick:

One really fun feature of systemd-nspawn is the --bind-user= switch. If used it will make the specified user from the host (i.e. user record + $HOME) available inside the container. It's a really simple way to quickly get shared access to your home dir from host and container.
With v259 the same option is now available for systemd-vmspawn too. Or in other words, …

Over the past months and years, systemd as acquired a number of features in the verified boot/TPM area. Verified boot means basically that in cooperation with a TPM a secure log is kept of what happens during runtime and in particular during boot, specifically that every component takes a hash value of the next component it starts (this is called "measuring").
