Re: Without Systemd

I'm looking forward to 2 or 3 years from now when we can look back and laugh at all the fear and apprehension about systemd.

That said though, I did just recently upgrade to Ubuntu 15.04 (which is all systemd now) and it is noticeably slower to boot up compared to my old upstart-based 14.04 LTS install. Hopefully there's some more optimization that needs to be done to bring the boot-up speed to parity with the previous versions.

I really like that you can now use systemd-cat with logfiles because regular cat doesn't fit anymore.

really unix philosophy, isn't it?

Surprising, what does `systemd-analyze blame` says ?

I'm not sure the systemd guys want to build with the unix philosophy. I don't have a definitive source (maybe SE radio podcast?) but I seem to remember one of the authors saying as much. They're more interested in what Linux can become than what unix was.

Not that I agree, but I believe that's what they said.

Oh neat, had no idea about that command. Looks like these two are the big time sinks:

6.340s systemd-udev-settle.service

6.232s NetworkManager-wait-online.service

Everything after that is under 250ms or so. Interesting that udev and network manager are taking so long during boot.

I'm still a systemd noob but I've heard there are ways to avoid blocking on network connectivity. Hopefully you'll forget about that part.

udev-settle seems to be a workaround LVM not being event driven enough http://freedesktop.org/wiki/Software/systemd/Optimizations/

Using arch, systemd boot time is now almost inexistant (but I have a tiny system with a SSD).

I have the feeling that things will settle into a Microsoft-like "things mostly work, most of the time, because so much effort was put into it rather than good design" kind of world. Sort of like how PulseAudio is now.

Most people are cool with that kind of OS, so I don't think there will be much more than occasional grumbling. People like me who can't stand it will all have left.

Lennart Poettering has a different view on Unix philosophy, it's more 'make it interesting and do what you need to'. I think nobody is right or wrong. This is all growing pain and, as I often say, at the right time I'm sure there will be tinier systemd-like built to be more Unixy (as in 'small set of smaller composable tools').
