Package: user-mode-linux
Version: 2.6.16-1um-1
Severity: grave
Justification: renders package unusable
I reported on the UML mailing list that I was unable to boot from an ISO
image, even after various gyrations. Jeff Dike suggested that the binary
was probably compiled without proper block support (specifically
CONFIG_BLK_DEV_UBD, although there may be issues with ISO9660 support as
well).
Here is the actual error and command-line:
