A healthy body is generally disease free.
An unhealthy body often has some disease or another.
In this case, a product called SystemD has spread amongst the open-source Linux community.
This software project brought in designs proven to be bad and insecure in technology as seen in products such as Micrsoft Windows.
Note that this is not specific to Microsoft Windows it is more to say that Microsoft Windows is a prominent example of this flawed and insecure design paradigm.
There are two major aspects of this System Disease that have infested Linux.
- The divide and conquer troll like community
- The infectious nature of the technical SystemD design.
If SystemD were like any other open-source project, then people would simple use it or simply not use it.
Very few people would really care what another person uses in their Distribution.
However, for whatever reason, trolls came out of the wood works to attack, harass, and polarize the open-source community.
This caused SystemD to get more attention than it would have and actually helped to expand its popularity, despite its inherit technical flaws.
To make matters worse, many Distributions already had a core design and a thriving community.
A community that already provided what they were looking for but now were being forced to change the entire foundation of their Distributions.
This not only made many of their own users unhappy, it also further polarized the open-source community.
And thus began the first symptom of the System Disease.
As with all diseases, the normal healthy functions that had previously worked began to function improperly.
The System Disease started requiring other software, unrelated to SystemD, to suddenly require support for SystemD in order to function properly or at all.
This is the hallmark of a virus where the project requires other projects to adopt its design.
Which then forces even more projects to have to support the virus.
If anything, one could call SystemD one of the most dangerous software viruses in Linux Distributions at this time.
Distributions designed for small Personal Computers, like the Pinephone have suffered significant problems due to the System Disease.
The Post Market OS is one such example where the small team managing the project could no longer sustain the efforts needed to gut out the System Disease from the various projects that used to work in Linux without caring about what system initializer software is being used.
The Post Market OS has had to abandon their previous effort and instead embrace SystemD.
The Linux From Scratch team has even been forced to change the future direction of their project.
Consider this quote from the February 1, 2026 Future direction for LinuxFromScratch announcement
"With some regret, LFS/BLFS will no longer be developing the System V versions of the books. ... As a personal note, I do not like this decision. To me LFS is about learning how a system works. Understanding the boot process is a big part of that. systemd is about 1678 "C" files plus many data files. System V is "22" C files plus about 50 short bash scripts and data files. Yes, systemd provides a lot of capabilities, but we will be losing some things I consider important." by Bruce Dubbs.
Abandoning their own community and embracing SystemD in turn further fractures the open-source community, fragmenting them into smaller groups that cannot independently sustain all of the software that is needed in this day and age due to the ever increasing complexity of software.
