Qubes defaults to Fedora on Xen, which is systemd. I don't trust anything related to the Government/Corporate system known as Red Hat, including that distro (Fedora) on which I've been pwnd while using. Redhat's rpm packages are well put together and the default config files that ship with them are very well designed and documented/commented. It rarely crashes, is super stable, and the packages are default working and have good configs. However I can tell you from personal experience that I won't get into that CentOS,Fedora and Redhat are not to be trusted at all.

Systemd is very easy to use, but again read the above about Redhat. Redhat and all of it's derivatives have implants that are virtually undetectable. I don't trust systemd, although I use it on Parabola GNU/linux, and I use openRC on Gentoo.

I have 6 computers running parabola on systemd (2 servers, 3 workstations, and a laptop). I have 1 computer running on Gentoo which I work on every once and a while. Also another laptop running Debian. I have 4 computers running OpenBSD 6.0 1xamd64 2xSparc64, and 1xAlpha. I also have an experimental computer running openIndiana on amd64. I'm sticking mostly wth parabola for day to day and server stuff, due to ease of maintainence. For me minimalism is the key to a solid foundation. Systemd's expansion in taking over other system components is a cause for concern.

"Critics say it’s not Unix-like Many of the complaints to systemd stem from a feeling that this huge project is increasing in scope and taking over too much of the Linux system. Not surprisingly, the Boycott systemd site starts with this exact complaint: “Systemd flies in the face of the Unix philosophy: ‘do one thing and do it well,’ representing a complex collection of dozens of tightly coupled binaries. Its responsibilities grossly exceed that of an init system, as it goes on to handle power management, device management, mount points, cron, disk encryption, socket API/inetd, syslog, network configuration, login/session management, readahead, GPT partition discovery, container registration, hostname/locale/time management, mDNS/DNS-SD, the Linux console and other things all wrapped into one.” Ubuntu’s Mark Shuttleworth originally called systemd “hugely invasive and hardly justified” when Ubuntu was sticking with their own “upstart” init system. Ubuntu eventually gave up that fight and is switching to systemd. The change will show up in the Ubuntu Desktop Next images starting in the 15.04 update cycle."

I'm very suspicious about it. And when I have free time i'm going to eradicate it and other questionable system components from off of any mission critical systems.

I hope that answers your question. I'm no expert and those are just my feelings on the subject.
