I ran systemd 219 with most recent patches and -PAM -AUDIT -SELINUX -IMA -APPARMOR -SMACK +SYSVINIT -UTMP -LIBCRYPTSETUP -GCRYPT -GNUTLS -ACL -XZ -LZ4 -SECCOMP +BLKID -ELFUTILS +KMOD -IDN
and, to compare, with +PAM +AUDIT +SELINUX +IMA -APPARMOR +SMACK +SYSVINIT +UTMP +LIBCRYPTSETUP +GCRYPT +GNUTLS +ACL +XZ -LZ4 -SECCOMP +BLKID +ELFUTILS +KMOD +IDN Checking memory RSS usage with 'sudo pmap -x -p 1' as suggested by Mantas, the former case uses about 5 MB, while the later consumes close to 9 MB. I'm sure that with statically compiled kernel and appropriate fstab that KMOD and BLKID are not needed either, but I doubt that they affect memory usage much. http://freedesktop.org/wiki/Software/systemd/MinimalBuilds/ says that the minimum requirements are udev and journald. I wonder if udev is really needed if the kernel is completely statically compiled and module loading is disabled? That is a common use case for many embedded devices.
