Manjaro isn't that fragile on its own. No, seriously, their goal is to make a stable version of Arch. No wait stop laughing —
The majority of issues with Manjaro itself (notwithstanding the team's other issues) would be fixed by retiring the AUR as an official software source altogether. It simply isn't a repository built with Manjaro's slower burn in mind; it demands a bleeding edge system. If you don't use the AUR, Manjaro is as stable as any other system. It just sucks for many other reasons, which is why I personally wouldn't use it.
Is it really that bad? Had manjaro as daily driver for about 4 years and the only time I broke was when I tried dangerous stuff xD. The main argument I keep hearing, is the they had invalid certs on their site. Is there anything else? Back ten it seemed like a great ateway into arch. Not using arch BTW. :-P
I used it as a daily for about 2 years. The cert issues is just negligence but I had major package breaking and found the NVIDIA configuration they used to be broken.
Looked great and ran awesome on first install it felt like if you don't update right away you're gonna hurt.
