Thanks, That's a good question. I don't know. I suspect that they are. In Debian we're focused on reproducibility with the same build environment. I don't think varying things like LANG would be useful to verify the available binaries were built from the published source, which is, I as understand it, is the primary purpose for reproducible builds. On a possibly related note, recent versions of man now produce a stack of warnings for postconf.f (this is the first one, there are 244, one for each line of the man page): warning: cannot select font 'C' [usr/share/man/man5/postconf.5.gz:1] As I understand it, the troff variant used that's normally used has never supported 'C', but didn't previously raise a warning. I looked into what font should be selected instead and the current answer seems to be don't set a font. Rewrite man pages so it's not needed. Here's one example: https://github.com/jgm/pandoc/issues/9020#issuecomment-1692680356 That's the point at which I decided it was more than I cared to think about over the weekend. FYI (and I totally understand you might decide the same on a longer term basis).
