Hm, I would swear up and down that I tried exactly that several times and
got odd error messages. Trying it now, however, still doesn't appear to do
what I need - setting the variable to "server1,server2" yields the
following output
triggering load callbacks
* 2013-08-17 17:22:59 executing `deploy:cleanup'
* executing "ls -xt /path/to/releases"
servers: ["server1"]
[server1] executing command
command finished in 512ms
*** no old releases to clean up
It doesn't try to remove old releases on server2.
