Comment 2 Adam Williamson 2010-02-25 16:51:02 UTC
this comes at the end of the live install process (after 'making post-install changes to file systems' or whatever it's called), when using dlehman's swap.py fix for https://bugzilla.redhat.com/show_bug.cgi?id=567840 .

Comment 3 David Lehman 2010-02-25 19:04:41 UTC
Patch for 567840 revised to prevent this failure as well.

Comment 4 Adam Williamson 2010-02-27 01:21:00 UTC
confirmed, works in alpha rc4.
