Tried a vanilla upgrade and it does indeed appear working again with 5.10.5-167. Thanks @mjn for the debugging.

FWIW booting with 5.10.1-162.current works too.

I'm "having multi-monitor issues" after update as well. Scenario is a little different but result appears consistent with this report (hard reset required). I can spin this out to a separate item if I get more debugging detail.

Alternative (safer) workaround is to install vulkan-devel which adds the same symlink

Apologies if I politicised this! IMO, Solus should have a cron package available for users, if nothing else to help onboarding (Hi!)

• dcron seems perfectly mature. Per its intention to be an implementation of the fundamentals only, I doubt it has needed many updates.
• cron is the original and even more "stable"
• cronie is the more (RedHat) maintained alternative.

1. It's a bash script, that is the source !
2. Just "backing up my work"

Easiest packaging ever:
