When I started in Linux full-time, back in the early 2000s, I was presented with different fs options - the installer did not give me any information on benefits, or on which ones were considered "stable". ext2 was available, but it also had a built-in version number, and I feared that once ext3 eventually rolled over, it might be incompatible. So I chose the fs that came with a name attached: ReiserFS. If someone was willing to attach their name to their code, I figured, that must be some quality code.
ReiserFS served me well, even though it always was a system lurking in the background. I was not a storage specialist. I was just a guy doing work on a Linux desktop, and ReiserFS "just worked". Occassionally, I put in a new disk, and watched the progression of other fs. Eventually, I switched over to ReiserFSv4.
Fast forward a few years, and the whole murder thing happens. Immediately the thing that made ReiserFS stand out for me becomes radioactive - the name is burnt. And I see distros slowly phasing out advertising the option of having a ReiserFS partition. Yes, it was still there when you searched for it, but it didn't feature prominently in the installers anymore. And it is obvious that the code becomes stale - arguably understandable, who would do OSS work on code that is branded the name of a murderer?
Twenty years later, I am still a Linux user. The last ReiserFS disk got shredded a year ago. Feels like the end of an era.
Lessons learned: Naming matters. If you attach your name to something and want that project to survive, maybe do not commit violent crimes.
