I'll summarize as best I can: BLFS uses multi-core build (make -j ...) for LO which is an excellent idea (IMHO). However, I found the book line which tries to implement that --with-parallelism=$(getconf _NPROCESSORS_ONLN) 1. UNnecesary: LO uses 'make -j <with the same value as above>' _by default_ (behind the scenes). I also added these two points: 2. Confusing to some (a personal opinion, this time - as opposed to the fact above) 3. Ugly, especially in the context ( again, personal. In the eye of the beholder) I also said that 4. For people (like Bruce and Simon) who would like to throttle down their machines for heating reasons, they can simply _add_ a simple, "clean" line: --with-parallelism=<desired number of cores to put in play> which _will_ be honored by LO. Example: you have 8 cores but --with-parallelism=3 # I allow only three cores to work in parallel 2. You built LFS, but you are scared about dollar signs ?

It was meant to reinforce my technical point that that kind of line was superfluous.

I thought I might need to send some stuff in a cleaner manner (i.e., not "detracting" from the main subject). Even as a general inquiry. As I hoped I made it clear in the post, I really didn't know how to do that (and I still don't.) In short, howto to this list vs in a "regular" E-mail to a personal addressee. Cheers, -- Alex
