[systemd-devel] Configuring systemd to build systemd-tempfiles in Yocto

[Dave Glenton]

Sorry if this question is covered elsewhere, but a couple of days of googling and experimentation has failed to find a solution and hopefully someone in this list can give me some pointers.

I am trying to configure an Open Embedded Yocto Linux build based round systemd version 249.7, however the resulting image is missing a number of binaries in the /usr/bin directory, specifically systemd-tmpfiles which is present on my Ubuntu 20.04 build machine.

I believe there should be parameters you can pass at build to configure what is generated, but I am struggling to find any documentation as to what they are and how you pass them to Meson / Ninja.

If I run systemd --version I get the following on Ubuntu

systemd --version
systemd 245 (245.4-4ubuntu3.15)
+PAM +AUDIT +SELINUX +IMA +APPARMOR +SMACK +SYSVINIT +UTMP +LIBCRYPTSETUP +GCRYPT +GNUTLS
+ACL +XZ +LZ4 +SECCOMP +BLKID +ELFUTILS +KMOD +IDN2 -IDN +PCRE2
default-hierarchy=hybrid

on this on Yocto

systemd 249 (249.7+)
-PAM -AUDIT -SELINUX -APPARMOR +IMA -SMACK +SECCOMP -GCRYPT -GNUTLS
