It's considered dormant by distrowatch due to not being updated in the past two years. however since it is based and compatible to Slackware stable it won't be updated until a new Slackware release.

It's hard to find solutions when you need them.

Since it is KISS you have to deal with more configuration than on other distributions.

Since it follows slackware releases.

Sure it is a lot more comfortable due slapt-gets package dependency resolution however you still have to do many stuff by hand, for example: If a package is updated you have to check manually if the old config still works with the new package version.

Hasn't been updated in 3 years.

Take a look at the forum. The most popular section in terms of topics and posts is the problems section!

I urge you to take a look at the last blog post, which at this point was from July 2019. It seems, the development team is tripping over their own feet, not knowing how to use a proper display manage with their outdated system. The website doesn't have an imprint or privacy policy...

There's probably no other distro that would use claws mail client, parole media player or exaile music manager as defaults.

Primary use for desktop and that's it.

Compared to other distros, narrow package choices.

Compared to other distributions the documentation is quite poor.

Graphical installer doesn't even work well.

Salix just can't keep up with other options. It's not as versatile, up-to-date, user-friendly, well-documented, versatile, popular or even as good looking as many other distributions these days.

Salix does not customize the UI and will ship an almost vanilla desktop.

Most other distros would provide images that can be used with USB thumb drives, which are way faster than outdated CDs and DVDs. Not Salix. The image is just as outdated as the rest of it.

Most distros these days would use systemd. Not Slax. I've used init in the 90s. But probably goes well with the missing upgrades of the past 3 years.
