Subject: [PATCH] Update common submodule
Pick up the commits below. In particular this makes several
refinements to the Windows firstboot code to make it more reliable.
Fixes: https://issues.redhat.com/browse/RHEL-55824
Ben Brown (1):
Initialise bar->fp as NULL
Richard W.M. Jones (16):
mlcustomize: Update virt-customize generated files
options: Allow nbd+unix:// URIs
mlcustomize: Add virt-customize --inject-blnsvr generated files
mlcustomize: Add Inject_virtio_win.inject_blnsvr implementation
mlcustomize: firstboot: Use Linux path for Powershell script path
mlcustomize: firstboot: Use powershell.exe instead of path
mlcustomize: firstboot: Use Powershell -NoProfile flag
mlcustomize: Revert delay installation of qemu-ga MSI
mldrivers/linux_kernels.ml: Prefix general information with ^info:
mlcustomize: Use Start-Process -Wait to run qemu-ga installer
mlcustomize: Add Firstboot.firstboot_dir function
mlcustomize: Place powershell scripts into <firstboot_dir>\Temp
mlcustomize: Inject qemu-ga & blnsvr into <firstboot_dir>/Temp
mlcustomize: Write qemu-ga log file name to log.txt
mlcustomize: Add some comments to firstboot batch file
mlcustomize: Reboot Windows between each firstboot script
