Or, whack the file and don't bother with a printk either. If it's in your config, and your command line doesn't contain noautogroup, it's on, so the info is already present (until buffer gets full). That makes for even fewer lines dedicated to dinky sideline feature. Or (as previously mentioned) just depreciate (or rip out) the whole thing since systemd is propagating everywhere anyway, and offers the same functionality. For 3.7, a revert of 800d4d30c8f2 would prevent the explosion when folks play with the now non-functional on/off switch (task groups are required to _always_ exist, that commit busted the autogroup assumption), so is perhaps a viable quickfix until autogroups fate is decided? -Mike
