@pixelb Does this simplify tests/tac/tac-continue.sh? Related with #9590 .

Well actually filling /tmp is dangerous on a normal machine. I'll probably adjust tac-continue.sh to be a root test that creates a small file system
Small FS based test would not work with uutils/tac as not using tmpfs. How about systemd-run?
Ofcause GNU's test suite is something for GNU coreutls, not uutils. But what can uutils do to test this?
Well $TMPDIR is part of the interface for tac, split, sort. I.e., would ideally be supported by uutils. How does uutils handle temp storage then for this use case?
Right, unbounded RAM usage is a bug, and generally TMPDIR has better constraints in place, or has more capacity than RAM
I'll probably adjust tac-continue.sh to be a root test that creates a small file system
