As upstream developers for UML, what would you conclude it as ? We've recommended using hostfs for the UML kernel modules as well. What would be the alternate approach to ensuring a proper boot for a modular UML kernel ? > I suppose that currently it does not work to mount hostfs later on. > No > idea what the right fix is.

The ability to mount any hostfs mount point was/is a feature provided by UML. We've used it and integrated with many tools like debos, fakemachine etc; the Debian bug report has the details. There'll be more reports following once UML 6.11 hits Debian Testing. I hadn't expected a working feature to break with a newer Linux release. :-( Thanks, Ritesh -- Ritesh Raj Sarraf | http://people.debian.org/~rrs Debian - The Universal Operating System
