>Release: NetBSD 5.99.14 iso-image from 20090627 autobuild
>Organization:
bozotic netbsd software testing labs
>Environment:
System: NetBSD 5.99.14
Architecture: i386
Machine: i386
>Description:
Boot the i386 installation ISO image. In sysinst select the utility menu
and run /bin/sh.
Enter the following commands
(
eval $(fdisk -S wd0)
)
The top-level shell hangs in "piperd". The job is suspendable with ^Z.
ps shows a zombie from the fdisk command hanging around.
The system in question is a PIII 866 MHz with 256MB RAM detected.
This is repeatable every time when immediately running /sbin/sh from
sysinst's Utility menue after booting into sysinst.
>How-To-Repeat:
see above.
>Fix:
dunno.

This bug report is > 12 years old now, and I cannot reproduce the
problem. Much has changed in the intervening 12 years...
Unless someone can show that there is still an issue that needs
fixing (or even just examining) here, I plan on closing this PR soon.

State-Changed-Why:
No longer occurs, 6 month notice (granted it wasn't in feedback)
I wonder if the problem was actually that pipe splice issue, can't
remember the timeframe when that was a thing...
