dumping active file systems

[Mark Callow]

The new 4.2 dump/restore programs do all their stuff through the
normal block device interface and no longer do the inode mapping.
The "changes in 4.2" document (I think.  I don't have it handy
at home to check it is THE one) in discussing this says that it
makes the dump tolerant of changes in the file system during
the dump and implies that dumping of active file systems is
safe.
