DC Debian: Subcloud remote install - root parameter from grub console is not set correctly

[Kyle MacLeod]

Brief Description

DC Debian: Subcloud remote install - root parameter from grub console is not set correctly

Note:

    This issue might be an environment issue (something that might not be under our control)
    Condition to reproduce the issue: plug a USB on the subcloud (can be a wiped USB) and run remote subcloud install
        results: root parameter, from grub, is set to boot from USB device rather than from the virtual CD media inserted by RVMC

Severity

<Minor: System/Feature is usable with minor issue>

Note: we can set grub/root to boot from virtual CD device

Steps to Reproduce

Plug a USB in the server

run remote subcloud install

Expected Behavior

Remote subcloud install should complete successfully, the grub parameters should be set up correcly independently if we have a USB plugged in the subcloud

Actual Behavior

The remote subcloud install fails if we plug a USB in the server

Reproducibility

Intermittent

This issue was not observed in a other subcloud which also has a USB plugged.

    Fix grub search label to 'instboot'

    Change the grub boot label to 'instboot'
    for miniboot, since this is the expected label.
    We no longer see the log:
    "error: no such device: oe_iso_boot"

    Test Plan

    PASS
    - Boot hardware subcloud, verify that the
      subclould boots and we no longer see
      "error: no such device: oe_iso_boot"
