[one-users] Error in "onevm list":`get_history_host':undefinedmethod `[]' for nil:NilClass(NoMethodError)

[Tino Vazquez]

Hi Alvaro,

Our installer is really simple at the moment, it just create links to the
compiled binaries.

If you untar the source over the previous source directory, you just need to
recompile it and there is no need to reinstall it again since the links now
will point to the new binaries.

If you choose to untar the source onto another directory and you want to
install it on the same $ONE_LOCATION, then you have to erase first all the
contents of $ONE_LOCATION.

Hope it helps,

-Tino
