took literally down my  whole network at times (on a ADSL connection)
such that i had to reboot the router.

it may  be useful to some, but i tend to avoid;

dont know what systemd does,
but experienced the passage from debian 7 to 8 and had such many problems and issues, that i tend to dislike it very much and ascribe the issues had to the software systemd, practically ruining a nearperfect linux experience (at the time).

I'm afraid you have misquoted me.
The quote belongs to the OP, kapqa.

I would never* spell systemd like that.  8^D !!!

* lest I summon an instant rebuke from our (long time) absentee member, HoaS.

In any case, Tailscale is a commercial service: so ask their support team and see what they say.

The Linux offering is significantly FOSS as far as I can tell so it is not entirely commercial IMHO - especially if used in conjunction with the Headscale project to replace the Tailscale "coordination" server!

Anyhow the issue is discussed as a "Feature-request" here on GitHub: https://github.com/tailscale/tailscale/issues/9502

It does entirely look as though the development of this product got sucked into the pool occupied by the systemd hydra...|

This post prompted by myself looking to go down this route for a (temporary) holiday setting involving using a fresh Raspbian OS install on a spare Raspberry Pi - with the unwanted init system which will be wiped out after the vacation (I'll accept the nasty on that unit for the duration but the rest of my boxen I'll treat as if they are fatally allergic to it!)

As tailscale does not seem to be in the Devuan repositories, I don't think there's a workaround.

Tailscale seems to be a WireGuard wrapper, and Devuan does have WireGuard in the repos, so one workaround might involve figuring out the config and using WireGuard directly.

Also, given the "it doesn't appear to be running" message, it's also possible it just uses systemd for running a service - if so the relevant service file can be converted to one compatible with [insert whatever kapqa's Devuan install is using for services].

In any case, Tailscale is a commercial service: so ask their support team and see what they say.

I don't see this package in the Devuan Package Information page.

Devuan Package Information page, so I have to assume that you downloaded it from another source.

Obviously, YMMV but it is usually not a good idea.

Chances are (99%) that you are right.

Well ...
You run Devuan 4.0.
Devuan is Debian without the systemd crap in it.

As tailscale does not seem to be in the Devuan repositories, I don't think there's a workaround.

have installed this service for accessing my NAS outside of the common homenetwork to which NAS is attached to.

now it seems it is not running on Devuan 4.0,
after installing it according to routine for "Debian Buaster"

manually like shown here
https://tailscale.com/download/linux/debian-buster

getting error

failed to connect to local tailscaled; it doesn't appear to be running

presume this is related to this system-d thing, have no other explanation.
is there a workaround for such issues?

thanks
