Last modified: 2012-05-19 19:50:13 EDT
Description of problem:
When carrying out an installation using a usb-storage device (for e.g. USB
floppy) the device node assigned to the device changes between the installation

inclusion in a Red Hat Enterprise Linux Update release for currently deployed
products. This request is not yet committed for inclusion in an Update

Moving to 4.7.
Yes, lack of engineering capacity. The device enumeration process works much
better in RHEL5 than 4 and I don't view this as that critical of a problem.
Worst case, we can document it in the release notes and make sure customers are
aware of what can potentially happen when USB devices are connected during
See comment #8. The amount of work this would require, combined with the fact
that this isn't really breaking anything, makes this a poor candidate for an
update so late in the RHEL4 product life cycle. This does seem like a good
candidate for a release note.
Development Management has reviewed and declined this request. You may appeal
this decision by reopening this request.
