initscripts do not touch cio_ignore.
Comment 3 Gonzalo Muelas Serrano 2010-09-14 06:21:18 EDT
the changes needed to implement this feature are to use the kernel
infrastructure (provided by RH Bug 631517) and the tool (provided by RH Bug
631527) in the scripts when booting the system to solve the issues workarounded with timeouts in RHEL 6.0. For more deatils, please read RH Bug 533494 comments #15 through #35, and get in contact with Dan Horak.

If the boot process just call some scripts done by Dan Horak, then is fine with me to reassign it to Dan Horak.
Comment 4 Steffen Maier 2010-09-14 08:41:18 EDT
This one is a follow-up on
RH Bug 561339 - [LTC 6.0 FEAT] 201085: unmask and wait for devices, initscripts part
which was originally created for initscripts but ended up in s390utils being triggered by an upstart event early during boot. Sorry for the confusion.

A new kernel interface to reliably block until dynamic free of devices from cio_ignore helps removing no longer necessary waiting loop code from device_cio_free and thus improves maintenance of this s390utils tool.

In order not to loose this part of the feature, reopening and reassigning to s390utils.

Close this feature request as duplicate
to   66875 - RHBZ 631527 -  [6.1 FEAT] Provide userspace handle to wait for cio
pending work - userspace

The functionality could be implemented into s390tools (s390utils) only and get referred to during install and boot.
The calls from installer and scripts already exist with RHEL6  (6.0 FEAT cio_ignore...)  feature request.
So nothing to implement for initscripts anymore.
