thanks for reporting. This problem was masked on my system
because the cache directories are created when the format is
built. Apparently there’s a thinko in the code that chooses a
writable path; I’ll report it to Hans.

TEXMFHOME isn’t used, at least not directly; the font loader
checks TEXMFCACHE, TEXMFVAR, and VARTEXMF (in this order) and
will (should) pick the first writable one.
