I see the reason for the complains, but I do not agree with the basic premise. It should not be "I hate almost all software", it should be "I hate my employer and the job I am stuck in".
I mean, this person is writing for Solaris/Illumos (judging by SMF references and autoconf complains). Yeah, running modern stuff on solaris sux, unless you have a sysadminny mindset. This is clearly not for him. Fine -- different people like to optimize different things: user experience, internal code beauty, maintainability, code robustness, number of platforms supported.
No one should be forced to work on stuff they don't like. There are lots of jobs, and most of them do not require SMF, DBus, /usr organization, or volatile variables.
