Reiser4 Internal Abstraction Layer

Filed under
Linux

The ongoing discussion about the Reiser4 filesystem [story] continues on the lkml. Jeff Garzik discussed the complexity introduced by a plugin layer [story], suggesting it is really a second VFS, "furthermore, it completely changes the notion of what a Linux filesystem is. Currently, each Linux filesystem is a tightly constrained set of metadata support. reiser4 changes 'tightly constrained' to 'infinity'. While that freedom is certainly liberating, it also has obvious support costs due to new admin paradigms and customer configuration possibilities."

Linux creator Linus Torvalds weighed in on the discussion, "as long you call them 'plugins' and treat them as such, I (and I suspect a lot of other people) are totally uninterested, and in fact, a lot of people will suspect that the primary aim is to either subvert the kernel copyright rules, or at best to create a mess of incompatible semantics with no sane overlying rules for locking etc." He went on to add, "as far as I'm concerned, the problem with reiser4 is that it hasn't tried to work with the VFS people.

Bill Wear, Developer Advocate for MAAS: foo.c

I remember my first foo. It was September, 1974, on a PDP-11/40, in the second-floor lab at the local community college. It was an amazing experience for a fourteen-year-old, admitted at 12 to audit night classes because his dad was a part-time instructor and full-time polymath. I should warn you, I’m not the genius in the room. I maintained a B average in math and electrical engineering, but A+ averages in English, languages, programming, and organic chemistry (yeah, about that….). The genius was my Dad, the math wizard, the US Navy CIC Officer. More on him in a later blog — he’s relevant to what MAAS does in a big way. Okay, so I’m more of a language (and logic) guy. But isn’t code where math meets language and logic? Research Unix Fifth edition UNIX had just been licensed to educational institutions at no cost, and since this college was situated squarely in the middle of the military-industrial complex, scoring a Hulking Giant was easy. Finding good code to run it? That was another issue, until Bell Labs offered up a freebie. It was amazing! Getting the computer to do things on its own — via ASM and FORTRAN — was not new to me. What was new was the simplicity of the whole thing. Mathematically, UNIX and C were incredibly complex, incorporating all kinds of network theory and topology and numerical methods that (frankly) haven’t always been my favorite cup of tea. I’m not even sure if Computer Science was a thing yet. But the amazing part? Here was an OS which took all that complexity and translated it to simple logic: everything is a file; small is beautiful; do one thing well. Didn’t matter that it was cranky and buggy and sometimes dumped your perfectly-okay program in the bit bucket. It was a thrill to be able to do something without having to obsess over the math underneath. Read more Also: How to upgrade to Ubuntu 20.04 Daily Builds from Ubuntu 19.10
