luaotfload uses different caches. The one `luaotfload-tool -u -f`
regenerates is the name caches containing all fonts on the system
(usually found under
$TEXMFVAR/luatex-cache/generic/names/luaotfload-names.*)
while `luatex-cache/generic/fonts/otl` is a separate cache used during
font loading. It does not get regenerated by `luaotfload-tool -u -f` and
it's expected to be empty if you haven't compiled documents in LuaLaTeX
with TL 2024 yet.

Can you test if fonts are found if you compile a simple document with
LuaLaTeX?

The arguments here don't seem very useful. Did you mean

> strace -eopen luaotfload-tool -u -f

In any case I would expect most systems today to use openat over open,
so can you try running

> strace -e openat luaotfload-tool -u

and see if that accesses more font directories?

Not sure why you say that the version number wasn't bumped, but that
commit is the luaotfload v3.27 release. I did cause some issues on
Windows, but they should be resolved by luaotfload v3.28.

In any case it can't be reverted since without it luaotfload does not
find any fonts on Linux unless you have a single user install of TeX
Live.

Best,
