i) There's now a seperate field in struct logical_volume that stores the
...
allocation policy. This can currently take one of three values:
typedef enum {
ALLOC_NEXT_FREE,
ALLOC_STRICT,
ALLOC_CONTIGUOUS
} alloc_policy_t;
Notice that 'SIMPLE' has turned into the slightly more meaningful NEXT_FREE.
ii) Put code into display.[hc] for converting one of these enums to a
text representation and back again.
ii) Updated the text format so this also has the alloc_policy field.

Merge with text format branch.
...
Lots of changes/very little testing so far => there'll be bugs!
Use 'vgcreate -M text' to create a volume group with its metadata stored
in text files. Text format metadata changes should be reasonably atomic,
with a (basic) automatic recovery mechanism if the system crashes while a
change is in progress.
Add a metadata section to lvm.conf to specify multiple directories if
you want (recommended) to keep multiple copies of the metadata (eg on
different filesystems).
e.g. metadata {
dirs = ["/etc/lvm/metadata1","/usr/local/lvm/metadata2"]
}
Plenty of refinements still in the pipeline.
