Ted Ts'o: For those who believe the systemd developers are reasonable and will listen to constructive criticism.....
Systemd intercepts kernel 'debug' boot parameter, floods dmesg, makes system unbootable. Or as Linus puts it in his summary:
Linus Torvalds
+Paul Morgan I think what you (and others) seem to miss is that the systemd people made the "debug" option that we introduced not just do something - but do something useless that actively broke other peoples use of that option.
It doesn't matter who "owns" it, the fact is, they broke it.
Ok, fine. Bugs happen, and that's not what makes people upset.
What makes me (and others) upset is that when the bug is reported, with explanations and a suggestion for how to fix it, Kay just closed the bug-report, claiming it wasn't a bug.
