2 Utilities to create a setup made of 2 different builds
3 read : 2 different node flavours
4 so that each myplc knows about the nodeflavour/slicefamily supported
7 This would be the basics for running tests on multi-node myplc,
8 in particular for node upgrades
11 #################### WARNING
13 # this feature relies on a few assumptions that need to be taken care of
14 # more or less manually; this is based on the onelab.eu setup
16 # (*) the build host is expected to have /root/git-build.sh reasonably up-to-date
17 # with our build module, so we can locate partial-repo.sh
18 # this utility needs to be run on the build host so we can point at a PARTIAL-RPMS
19 # sub-repo that exposes the
20 # bootcd/bootstraps/ and the like rpms from one flavour to another
22 # a utility to create a bonding_plc_spec from
23 # a plc_spec and just a buildname
