Oh, please. systemd is flat-out tiny compared to Linux, which actually is
monolithic. I found an article from 2014[1] stating that systemd reached
550,000 lines of code. Linux 4.1 has over 19.5 million lines of code.[2] And
as has already been said before, systemd is a collection of about 60 separate
programs, so the average number of lines for a given systemd program is less
than 10,000. Linux is about 2,000 times bigger than any given systemd
component.
So, clearly, you need to stop using Linux. Also, you clearly need to stop
using anything compiled with GCC, which is also much bigger than systemd; 7.3
million lines in 2012.[3]
