[systemd-devel] Does Systemd also mount sysfs, procfs?

Precisely.  /proc and /sys are created by the Linux kernel before 
userspace represented by 'Pid Eins" even starts.  /proc and /sys are 
'virtual filesystems' that the kernel employs to communicate to 
userspace.

You figured it out yourself: good work.  For authoritative info, look at

https://www.kernel.org/doc/Documentation/filesystems/

under proc.txt and sysfs.txt.
