[one-users] hooks execution on remote nodes without shared ONE installation dir

[knawnd at gmail.com]

forgot to mention that I could not find any info in [1] too about a 
necessity to share $ONE_LOCATION/share/hooks dir across CNs in case if 
hooks has to be executed on remote node. So I wonder if 
$ONE_LOCATION/share/hooks needs to be available across CNs if there is 
hook to be executed on CNs or there is some built-in mechanism in ONE 
which transfers such hooks to CNs but for some reasons it didn't work in 
my case?

Nikolay
