argh!

i found this blurb on the 1.0.1 caveats page and looked for a link to the
1.1 caveats page to see if it still existed in the 1.1 release but could
not find a link.  i even guessed at some possible urls to no avail.

thanks for the info.

i have attempted to use xfs_growfs to change the log to an external log 
but cannot.  any idea when this functionality will be available?  not that
it makes any difference since i can't wait any longer on this issue.
