updating cloud-init cicustom file is not reflected on cloud-init drive

[halradaideh]

I am trying to change some configuration in the cicustom file for cloud init, but doing so (using the terraform provider) requires recreation of the VM updating the file manually is not reflected in the zfs volume of cloud init. when I try to mount it it is write-protected so I think it is a deadend

can you please make the update of cicustom file reflectable on the cloud-init volume

PS: I've tried to remove readonly using zfs command and using hdparm but nothing worked.
