Hi Jean-François,
TEXMFROOT is defined in


Its value is relative to the location of the binaries.  TeX Live sets


because binaries are in .../bin/<platform> and Linux distributors set


because they only support one platform.  The value of TEXMFROOT should
never be an absolute path, otherwise your TL installation isn't
portable anymore.

Kpathsea variables can be overwritten by environment variables.  Does
your environment overwrite TEXMFROOT?
