Hi,
At present cloud-init stores data in /var/lib/cloud. For systems with
transactional-updates, i.e. opensuse-microos and other incarnations this
location becomes read-only.
Would it be OK to send a PR that moves the data to /var/cache/cloud ?
I'd prefer a wholesale move of the data over various if conditions and
checks whether or not /var/lib is writable. Also we'd know that as of
version X of cloud-init the data has been moved.
Basic idea is
if no os.exists('/var/cache/cloud'):
create_it
if os.exists('/var/lib/cloud'):
move_the_existing_data_to_new_location
Do the above early enough in the process such that for all other
locations in the code that access the data the change in location is
transparent.
Thoughts?
That doesn't make any sense. openSUSE systems are explicitly supposed
to omit /var from the read-only root. That's why the RPM and DNF
databases were moved to /usr years ago. The whole point of /var is for
system specific data. It is supposed to be always writable.
