Linux Over the past year I've been reading a lot of opinions on the new init technology, systemd. Some people think systemd is wonderful, the bee's knees. Others claim that systemd is broken by design. Some see systemd as a unifying force, a way to unite the majority of the Linux distributions. Others see systemd as a growing blob that is slowly becoming an overly large portion of the operating system. One thing that has surprised me a little is just how much people care about systemd, whether their opinion of the technology is good or bad. People in favour faithfully (and sometimes falsely) make wonderful claims about what systemd is and what it can supposedly do. Opponents claim systemd will divide the Linux community and drive many technical users to other operating systems. There is a lot of hype and surprisingly few people presenting facts.

Presumably these are all statically linked into the binary so that emergency booting is possible (like if I cannot mount /usr or /var or something else important).


Under Red Hat 7, the combination of systemd and Fedora's "improved file layout" (ie, move /bin into /usr/bin) means if you have a system that has /usr on a separate partition-- It cannot be upgraded to Red Hat 7, and may or may not work (systemd relies on /usr being available when it starts).

Minor issue in the grand scheme of things, but it means my group can't upgrade any of our servers in-place to RHEL7.

Does make you wonder about the size of the initramfs, though.

There are ways around the /usr thing, but it depends on using a initramfs that do the initial boot and mount of /usr.

I think their plan is to use this for cloud VMs, so that a shared /usr can sit on a SAN and be mounted by any number of minimal VMs as they are spun up by the load balancer.

Frankly all that is coming out of systemd and Gnome these days seems oriented at two things.

1. cloud computing.
2. multi-seat government/military installations.

For either of these the feature set of systemd is pure gravy. but for most outside of that it is straight overkill.
