You should add some >/dev/null, else this might show up on %post..

I do not think this will work in the context of SUSE CaaSP or openSUSE Kubic

During a transactional update (the only supported mechanism for updating or installing this package), /var is not mounted

Therefore "! findmount /var" will fail

Therefore it will try and make a /var/lib/cni subvolume with the subvolume of the transactional update

This will then be override by the /var mount on CaaSP and Kubic, but that will not have the directory created

That means in CaaSP or Kubic the entire if findmnt -t btrfs block seems like a no-op that will not accomplish anything you need accomplished

Have you tested this on CaaSP or Kubic? can you please present the logs? Because there is no way I can see this working and would recommend we do NOT merge this.

Also, lines 14-15 don't make sense. You are requiring snapper if is_susecaasp, but using snappers mksubvolume on lines 26-27 regardless of whether or not is_susecaasp is true or not.

This does not address any of the issues raised in SR# 581729

For what it's worth - This is the code Thorsten and yourself provided us to do just this! Do you have an alternative suggestion?

we were wrong :) For what it's worth, I certainly didn't think about the implications of running this as part of a transactional update where all of the findmnt's me and thorsten suggested will not work.

But the implications are there - /var will not be mounted during a transactional update

findmnt -s /var (to read the /etc/fstab) might be a workaround

I'd really like to see some tests to make me confident this all works

Also, as this package is creating /var/lib/cni, it really needs to be defined in %files in the specfile - right now this package will be making the folder orphaned, which is really not good.
