Reproduction Steps

1. Use ignition file (attached as test.ign)
2. Dump it to cmd.exe variable: set /p ignit=<c:\test.ign
3. Set property: VBoxManage guestproperty set fcos /Ignition/Config %ignit%
4. Run VM. VM ignition failed

Other Information

Here is output of guestproperty get for verification:

'''
C:\Users\xxxx>VBoxManage guestproperty get fcos /Ignition/Config
Value: {ignition:{version:3.4.0},passwd:{users:[{name:core,sshAuthorizedKeys:[ecdsa-sha2-nistp384 XXXXE2VjZHNhLXNoYTItbmlzdHAzODQAAAAIbmlzdHAzODQAAABhBEpNUIlPBZW6HWAPaN7EnQ4i/91kIP4GRd+GctJqWIHB/3nFNhTcFb+9zTgzlcXfQhgd8S0XXXXXt3QXAHF+H4RUt0/TTcGyIlv0Mp69bRwLC0PnqfdeZZ/nix+xw6+bmw== main-ssh]}]},storage:{files:[{path:/etc/hostname,contents:{compression:,source:data:,fcos-test%0A},mode:420},{path:/etc/profile.d/systemd-pager.sh,contents:{compression:,source:data:,%23%20Tell%20systemd%20to%20not%20use%20a%20pager%20when%20printing%20information%0Aexport%20SYSTEMD_PAGER%3Dcat%0A},mode:420}]}}

I'm not able to verify how the ignition reads config inside the VM, because seems that it's not cached everywhere, just memory stream is used (analyzed source code). But seems that the ignition is corrupted by some way.

I have tried also to set the property value directly:

'''
VBoxManage guestproperty set fcos /Ignition/Config "{ignition:{version:3.4.0},passwd:{users:[{name:core,sshAuthorizedKeys:[ecdsa-sha2-nistp384 XXXXE2VjZHNhLXNoYTItbmlzdHAzODQAAAAIbmlzdHAzODQAAABhBEpNUIlPBZW6HWAPaN7EnQ4i/91kIP4GRd+GctJqWIHB/3nFNhTcFb+9zTgzlcXfQhgd8S0XXXXXt3QXAHF+H4RUt0/TTcGyIlv0Mp69bRwLC0PnqfdeZZ/nix+xw6+bmw== main-ssh]}]},storage:{files:[{path:/etc/hostname,contents:{compression:,source:data:,fcos-test%0A},mode:420},{path:/etc/profile.d/systemd-pager.sh,contents:{compression:,source:data:,%23%20Tell%20systemd%20to%20not%20use%20a%20pager%20when%20printing%20information%0Aexport%20SYSTEMD_PAGER%3Dcat%0A},mode:420}]}}"
'''

but result is completely same
