[PATCH] fixes to release_handler with sync'd relup-ing on inet boot loaded slaves

[Steven Gravell]

the slave starting part of the example should have been this

$ /path/to/slave1/target_system/bin/erl \
    -name slave1 ◎ hostname2 -id slave1 ◎ hostname2 \
    -loader inet \
    -hosts 9.9.9.9 \
    -boot /path/to/your/target_system/clients/slave1 ◎
hostname2/releases/1/*start* \
    -config /path/to/your/target_system/clients/slave1 ◎
hostname2/releases/1/*sys*
