Its the same with slackware 8.1 (2.4.18 kernel) with fileutils 4.0 &
textutils 2.0

Under RedHat 7.3, I get:
one
two
tail: test: file truncated
tail: test: cannot seek to offset 0: Illegal seek

That's with textutils 2.0.21 and fileutils 4.1

Now why does it work in RH, but not in Slackware? Perhaps Patrick
Volkerding would know?
