It might have been that I did not yet add the CloudInit drive in Proxmox yet.
A subsequent call to
slestemplate:~ # /usr/lib/cloud-init/ds-identify
did not yet yield a different result.
Only by analysing the source I found that it caches results and I can use the `--force` option to override this. I did this and the NoCloud datasource got detected properly. Apparently this is cached now.
The tool would only inform of the caching as a DEBUG message. However I set logging to INFO for all parts of Cloud Init as the FileHandler clutters the log with tons of messages how many bytes it read from each file. Sure, I could use INFO only for FileHandler.
Several issues reduce the ease of administration here:
1. Don´t cache errors. Really… just… don´t.
2. Don´t cache errors almost *silently* (just as a debug message).
3. Decide wisely what is a debug message and what is not.
cloud-init 18.2 from http:// download. opensuse. org/repositorie s/Cloud: /Tools/ SLE_12_ SP3/ on SLES 12 SP 3 with NoCloud data source via Cloud Init drive made by Proxmox.
On SLES 12 SP3 NoCloud data source was not working, despite
slestemplate:~ # blkid -c /dev/null -o export 05-15-16- 34-27-00
[…]
DEVNAME=/dev/sr0
UUID=2018-
LABEL=cidata
TYPE=iso9660
[…]
with necessary files on it. blkid gives 0 as returncode
Why?
I only kept parts of the output:

4. A search for `ds-identify` in the documentation available at https:/ /cloudinit. readthedocs. io/en/latest/ did not yield any result.
5. And in general: Keep it short and simple.
IMHO the first is the most important: Don´t cache errors. If the resource now is there, recognize it, without further discussion.
