Well, that was especially true for Minix 1 and 2. Minix 3 is purportedly a production operating system, and ships in every Intel CPU for the last decade or so, right? So while admittedly it may not have significant filesystem needs, it is not purely a teaching operating system anymore.

Nowadays I might point at MIT's xv6, which implements a very similar simple unix filesystem: https://github.com/mit-pdos/xv6-public/blob/master/fs.c

xv6 also was switched to RISC-V (not exactly sure when, but sometime in 2019), and it has a nice book for the actual course.

Course: https://pdos.csail.mit.edu/6.828/2019/xv6.html Book: https://pdos.csail.mit.edu/6.828/2019/xv6/book-riscv-rev0.pd...

Take a look at chapter 7 for the xv6 filesystem referenced here.
