Oh, is that so? 

Have you actually read the blog story I put together? 

Why do you say "cgroups are a dead end"? Sure, Scott claims that, but
uh, it's not the only place where he is simply wrong and his claims
baseless. In fact it works really well, and is one of the strong points
in systemd. I simply see no alternative for it. The points Scott raised
kinda showed that he never really played around with them.

Please read up on cgroups, before you just dismiss technology like that
as "dead end".

Well, please read the blog story. I know it's long, but it should be an

reason systemd exists is purely technical, and that we think our design
is simply the better one.

We didn't do systemd for political reasons.

We didn't do systemd just to do things differently.

We did systemd because we thought that technically Upstart is
fundamentally flawed and misses out on so many opportunities.

And if you cannot see that then I can only beg you to read the blog
story, because it goes into much detail about all the technical

Please, judge systemd on technical grounds, don't judge it on political,
or emotional grounds.

Thank you,
