The generation of cumulus osimage: copycds /iso/cumulus-3.5.2-armel/cumulus-linux-3.5.2-bcm-armel.bin determine the file ./cumulus-linux-3.5.2-bcm-armel.bin, if the output is data, it will perform the following 3 steps:

a. run “cumulus-linux-3.5.2-bcm-armel.bin” and get the binary information and generate the osimage name

 # ./cumulus-linux-3.5.2-bcm-armel.bin
 Verifying image checksum ...OK.
 Preparing image archive ... OK.

 Description: Cumulus Linux 3.5.2
 Release: 3.5.2
 Architecture: armel
 Switch-Architecture: bcm-armel
 Build-Id: bab9bc5z1d1b1f3
 Build-Date: 2018-01-31T00:41:00+0000

 Min-Disk-Size: 1073741824
 Min-Ram-Size: 536870912
 mkimage-version: cl3u13

b. copy the binary to the /install/cumulus3.5.2/cumulus-3.5.2-armel/

c. create the the following osimage definition

[root@c910f03c05k21 cumulus_mlx]# lsdef -t osimage -o cumulus3.5.2-armel
Object name: cumulus3.5.2-armel
    imagetype=linux
    osarch=armel
    osvers=cumulus3.5.2
    pkgdir=/install/cumulus3.5.2/armel/cumulus-linux-3.5.2-bcm-armel.bin  #<<< might be a comma separated list, the 1st should be the full path to the bin file
    synclists=/tmp/compute.synclist #<<<<<<<synclist specified here>>>>>>>>>>>>
    postscripts=xxxx
    postbootscripts=xxxx

nodeset mid05tor12 osimage=cumulus3.5.2-armel
```
[root@briggs01 ~]# lsdef mid05tor12
Object name: mid05tor12
    groups=switch,edge_switch
    ip=172.11.205.12
    mac=xx:xx:xx:xx:xx:xx
    mgt=switch
    netboot=onie
```
nodeset performs the following operations:

(1) find the "*.bin" file under the first entry in osimage.pkgdir, then copy the "*.bin" to /install/osimages/cumulus3.5.2-armel

(2)assign the node.provmethod to the osimage name

(3)run "makedhcp -a ", generate the dhcp lease with full path to the bin file in default-url option
add an option -r [the full path to scp or rsync] for updatenode to select scp/rsync, refine the code logic in updatenode and xdcp to enable this
```
# updatenode mid05tor12 -F -r /usr/bin/scp
# xdcp mid05tor12 -F -r /usr/bin/scp
```
refine the code logic in startsyncfiles.awk , add an option -r to select the scp or rsync, the compute node can select the scp/rsync according to the existence of the 2 executables
```
# syncfiles -r usr/bin/scp
```
