hi,

I've been using py38-cloud-init, and now py39-cloud-init in conjunction with Xen Orchestra:

https://xen-orchestra.com/docs/installation.html#xoa
https://xoa.io/deploy

Originally with py38-cloud-init, and now py39-cloud-init, I'm applying the following change:

sed -i '' -e 's/            gid = grp.getgrnam(group).gr_gid/            pass #20220224 this comment added in packer builder. bug?: gid = grp.getgrnam(group).gr_gid/g' /usr/local/lib/python3.9/site-packages/cloudinit/util.py


Unless I make that change, a corresponding cloud_init with eg:

write_files:
- content: |
   some-script-here
  path: /root/some-script.sh

or

write_files:
- content: |
   some-script-here
  permissions: 0744
  path: /root/some-script.sh

write_files:
- content: |
   some-script-here
  permissions: "0744"
  path: /root/some-script.sh

doesn't appear to be handled correctly. Example error message: from /var/log/cloud-init-output.log is:

util.py[WARNING]: Running module write-files (<module 'cloudinit.config.cc_write_files' from '/usr/local/lib/python3.9/site-packages/cloudinit/config/cc_write_files.py'>) failed

I am successfully using cloud-init with the same xen/xen-orchestra & other operating systems, for example alma linux, without needing to apply this change. 

Please let me know if there is further information I can provide. Alternatively, also let me know if you believe this issue should be submitted upstream with cloud-init team directly.

Many thanks
