Indeed.
I never worked with this directly, though. I went to grad school
at Georgia Tech, where some of the students had started with the tools
from the book and built a beautiful Unix-like subsystem on top of
Primos on Pr1me minicomputers. (This code was recoverd in 2019,
after thinking it'd been lost for 30+ years!)
I never asked, but I suspect that the Georgia Tech guys simply didn't
know about the LBL work, or else they developed in parallel.

All you folks revisiting the Software Tools should
remember that there
was an entire movement around the first book, based at Lawrence Berkeley
Lab. The Software Tools group, an offshoot of Usenix, had about 2000
members. We created an almost-entire Unix environment based on a
virtual operating system that we designed, inspired of course by
Kernighan's ideas. The collection was ported to over 50 operating
systems, including some without file systems. This is all still freely
available, and stored with the Unix archives.
