Hi Philip,

Yes, which calls mktexfmt which is an instance of fmtutil.
Automatic format generation is putting files in TEXMFVAR, that has to be
like this since TEXMFSYSVAR might be not writable, even on Windows with
admin install.

Nobody told you so. The -sys works only for fmtutil and updmap.

Yes, this is correct and expected behaviour, and unchanged since Thomas
Esser introduced this distinction about 20+ years ago.

Yes, it can, by setting
to the value of TEXMFSYSVAR or your preferred value in the texmf.cnf I
mentioned in my last email:

I never heard that "personalual" is an English word.
