[one-users] when is ONE_LOCATION set?

Actually,

/var/lib/one/remotes/vmm/xen does *not* correspond to  
$ONE_LOCATION/lib/mads/one_im_exec

but to the $ONE_LOCATION/var/remotes/vmm/xen folder

as you see /usr/lib/one -> $ONE_LOCATION/lib
and /var/lib/one -> $ONE_LOCATION/var

In the install.sh you can see the correlations of folders:

system-wide
     BIN_LOCATION="/usr/bin"
     LIB_LOCATION="/usr/lib/one"
     ETC_LOCATION="/etc/one"
     LOG_LOCATION="/var/log/one"
     VAR_LOCATION="/var/lib/one"
     SUNSTONE_LOCATION="$LIB_LOCATION/sunstone"
     OZONES_LOCATION="$LIB_LOCATION/ozones"
     SYSTEM_DS_LOCATION="$VAR_LOCATION/datastores/0"
     DEFAULT_DS_LOCATION="$VAR_LOCATION/datastores/1"
     RUN_LOCATION="/var/run/one"
     LOCK_LOCATION="/var/lock/one"
     INCLUDE_LOCATION="/usr/include"
     SHARE_LOCATION="/usr/share/one"
     MAN_LOCATION="/usr/share/man/man1"

self-contained
     BIN_LOCATION="$ROOT/bin"
     LIB_LOCATION="$ROOT/lib"
     ETC_LOCATION="$ROOT/etc"
     VAR_LOCATION="$ROOT/var"
     SUNSTONE_LOCATION="$LIB_LOCATION/sunstone"
     OZONES_LOCATION="$LIB_LOCATION/ozones"
     SYSTEM_DS_LOCATION="$VAR_LOCATION/datastores/0"
     DEFAULT_DS_LOCATION="$VAR_LOCATION/datastores/1"
     INCLUDE_LOCATION="$ROOT/include"
     SHARE_LOCATION="$ROOT/share"
     MAN_LOCATION="$ROOT/share/man/man1"


Note that the LOG, RUN and LOCK folders default to $ONE_LOCATION/var in  
self-contained mode.

Thanks but as I see the docs are not 'broken'. It is easier to write, read  
and maintain the documentation without constantly making explicit mention  
of the install mode.

Yes yes, just as it would system-wide.
