Can't reproduce here. Since changing versions fixes the problem for you, I don't doubt that 
util-linux is somehow related to the problem, but without a way to reproduce it, there's 
nothing I can do to fix it. Patches/ideas welcome, otherwise you may want to just upgrade 
to a more recent release (it's worth trying the util-linux from 7.1/7.2 errata to see if that

The problem does not exist in 7.2 - thanks!!!
Comment 3 Phil Mayers 2002-12-18 09:46:33 EST
I've reproduces this with a serial line getty running from init - there appears
to be a weird code path in login - after open(2)'ing /etc/motd it does a read(2)
from FD 1 (stdout) - which is clearly wrong!

I've upgraded the machine to 7.1's util-linux, so assume the bug is fixed or the
odd code path isn't excercised for some reason, but I'll take a look at the
source in new year.
