6.5.3.MGBL

Description (partial)

Symptom:
- The  MINI ISO and RPMs and SMUs are merged to create a GOLDEN ISO. We see the correct file pointers in the sysadmin VM:

sysadmin-vm:0_RSP0# run
Thu Mar  12 09:03:52.619 UTC
 
sysadmin-vm:0_RSP0:~]$cd tftpboot/
sysadmin-vm:0_RSP0:~/tftpboot]$ls -la

drwxrwxrwx  3 root root       4096 Mar 12 09:03 .
drwxr-xr-x 10 root root       4096 Mar 12 07:58 ..
-rw-r--r--  1 root root 1978871808 Mar 12 07:37 asr9k-goldenk9-x64-6.5.3-0 <<<<<< Current active image
-rwxr-xr-x  1 root root 1684977664 Mar 11 15:52 asr9k-goldenk9-x64-6.6.3-0 <<<<<<<< inactive image
drwxr-xr-x  3 root root       4096 Mar 10 13:58 boot
-rwxr-xr-x  1 root root        637 Mar 12 08:47 grub.cfg
-rwxr-xr-x  1 root root     916590 Mar 12 08:01 grub.efi
lrwxrwxrwx  1 root root         28 Mar 12 08:47 system_image.iso -> ./asr9k-goldenk9-x64-6.5.3-0 <<<<<<<<< correct file linkage
-rwxrwxrwx  1 root root          0 Mar 11 16:12 zapdisk.log

- In the above outputs, we see both image files are ending with version "0" which is causing the issue and the remove command thinks the active/committed GISO has to be removed as well.
- When the "install remove inactive" is executed in the XR-VM we see that the 'current active image' ISO file also gets removed while the file pointer remains: 

RP/0/RSP0/CPU0:lab11#install remove inactive

Conditions:
