Ok, I don't know why there is a version skew but because the log is
nothing more than a log, it really is the data we care about, so there
is a way to `upgrade'.

I'll first explain where I'm trying to get to,

First make sure you create a backup copy of both the RVM log and the
data in case anything goes wrong!

We use the old `rvmutl' which should be able to access the old log
format to make sure all pending modifications are committed to the rvm
data (they should be, but you never know). Then the log can be recreated
with the new rvmutl.

Here we go,

# cp <rvmlog> rvmlog.backup
# cp <rvmdata> rvmdata.backup
# rvmutl.old <rvmlog>
* status
..
 log empty:             true
..
* q

( That was the optimistic case ;)

# rvmutl <rvmlog>
* status
..
 log empty:             false
..
* recover        (or recover <rvmdata> I'm not sure, manpage is unclear)
* q

( now we destroy the old log and recreate a new one. )
# rm <rvmlog>
# rvmutl.new
* i <rvmlog> 2M
* q

At this point we should have a useable log again.
