[I'd rather you kept me cc'ed as I am not subscribed to unison-users. I
will check the archive in the next few days though.]

Hello,

It seems that while rootalias affects the naming of roots for archive
name purposes, it does not affect their ordering (resulting in a .5
chance of not working). This was observed with unison 2.9.1.

The symptoms: I usually to synchronize files from cincle to puligny. I
wanted to use chianti or muscadet instead of puligny (the three share
their files with NFS). The following rootalias specification worked:

================ unison profile on cincle (excerpt) ================
root = cvsroot
#root = ssh://puligny/cvsroot
#root = ssh://chianti/cvsroot
root = ssh://muscadet/cvsroot
rootalias = //muscadet//home/beaune/moscova3/peskine/cvsroot -> \
//puligny//home/beaune/moscova3/peskine/cvsroot rootalias = \
//chianti//home/beaune/moscova3/peskine/cvsroot -> \
//puligny//home/beaune/moscova3/peskine/cvsroot ================ unison profile on \
cincle (excerpt) ================

However, using chianti as the remote host fails to find the desired
archive file (full trace attached). The relevant line seems to be:

[update] Archive name is \
//cincle//home/gilles/cvsroot;//puligny//home/beaune/moscova3/peskine/cvsroot, \
//cincle//home/gilles/cvsroot;17  i.e. 049a8fef5333743bef512ad37773b058

where as my archive file .unison/areb6044dc5ae0952367478b3fa0157fd3 shows:

Archive for root //cincle//home/gilles/cvsroot synchronizing roots \
//cincle//home/gilles/cvsroot, //puligny//home/beaune/moscova3/peskine/cvsroot



A few more minor points:

* The end of the trace (terminal capture) shows debugging output getting mixed
  up with normal output; looks like some flush calls are mising.

* When I first saw the warning, my reflex was to press Ctrl+C, which left locks
  lying around. I would have expected unison to abort gracefully on SIGINT.

* I found the manual confusing as to how to write the rootalias specification,
  in particular the fact that I had to expand the home directory on the remote
  machine.

No archive files were found for these roots.  This can happen either because this is \
the first time you have synchronized these roots,  or because you have upgraded \
Unison to a new version with a different archive format.  

Update detection may take a while on this run if the replicas are 
large.

Unison will assume that the 'last synchronized state' of both replicas
was completely empty.  This means that any files that are different
will be reported as conflicts, and any files that exist only on one
replica will be judged as new and propagated to the other replica.
If the two replicas are identical, then no changes will be reported.
