Debian has certainly more than 10%. Especially in small server space or embedded Linux many just install Debian because its a simple and stable option.

That does not change your point about systemd adoption. Debian has been in practice systemd only for how many years?

Debian has not in fact been systemd only; the GR that is being discussed in this thread replaces a decision by the Technical Committee from 2014:

https://lists.debian.org/debian-devel-announce/2014/08/msg00...

  For the record, the TC expects maintainers to continue to support
  the multiple available init systems in Debian.  That includes
  merging reasonable contributions, and not reverting existing
  support without a compelling reason.

However, in practice Debian users tend not to replace systemd's PID1 with the sysvinit-core package, as it is installed on a negligible fraction of Debian systems.

I'm not sure you can rely on popcon to make decisions like that.. anyone who doesn't explicitly opt in, and anyone who installs on a system with limited internet access (i.e. probably most enterprise users) won't be counted.

> I'm not sure you can rely on popcon to make decisions like that

I'd go further and say you definitely can't rely on popcon, for two main reasons:

1 - Not many sysadmins are happy to install a program that "phones home" at regular intervals about system usage.

2 - Popcon records file access times, so a server that runs for long periods between restarts or reboots shows init files are accessed infrequently. This skews the result towards desktop and laptop installations (which are most likely to use the default init).

> Debian has certainly more than 10%

And way more than 10% if we consider that Ubuntu is built on Debian.

Ubuntu doesn't have sysvinit so isn't relevant here.
