Bug#314334: This bug causes apt to break on OCFS2 too

["James Harper" <james.harper@bendigoit.com.au>]

I'm just testing OCFS2 as a root filesystem, and apt breaks because
OCFS2 (and probably GFS) don't support shared writable mmap's. For OCFS2
at least, this support is on the todo list but not really near the top.

Any chance of an updated patch or, even better, something that detects
at runtime what the underlying filesystem supports and adjusts
accordingly?

Thanks

James
