uutils-coreutils issue starting with Ubuntu 25.10:

Canonical replaced GNU coreutils (GPL) with uutils coreutils (MIT/Rust/Code of Conduct), which causes several issues, including problems with pseudo-host.
See Carefully But Purposefully Oxidising Ubuntu and
Ubuntu 25.10's move to Rust coreutils causes major issues for some executables.

Typical error: couldn't allocate absolute path for 'null'.

In general, uutils-coreutils is currently not recommended for Freetz builds due to immaturity and known issues in multiple tools (date, cp, mv, base64, du, sort, tail, ls, md5sum, dd, sudo, ...).

Workaround: remove uutils-coreutils and install GNU coreutils with
