What commenters say

• PID 0 is not a valid process ID, but rather a convention used in certain contexts, such as referring to the current process group or the idle process.
• The meaning of PID 0 can vary depending on the context and the specific system being used, and it is not always a straightforward concept.
• Some commenters argue that the article's explanation of PID 0 is oversimplified or incorrect, and that a more nuanced understanding of the concept is necessary.
• Others suggest that the article's use of the term PID 0 is a useful approximation, even if it is not entirely accurate, and that it can be a helpful way to understand certain aspects of the Linux kernel.
• There is a tendency for people to be overconfident in their understanding of technical concepts, and to present their views as definitive and absolute, even when they are not entirely accurate.
• The discussion highlights the importance of careful research and attention to detail when discussing complex technical topics, and the need to be aware of the potential for confusion and misinformation.
• Some commenters note that the concept of PID 0 is not unique to Linux, and that similar concepts exist in other operating systems, such as Windows.
• The use of confident language and tone can be misleading, and can give the impression that a particular view or explanation is more authoritative or accurate than it actually is.
