Comment 16 for bug 1728742

Ryan,

I did have a PPA added via MAAS though.

I looked at /lib/udev/rules.d which was incorrect - should have looked at /etc/udev/rules.d.

Now, with an entry in MAAS and in curtin_userdata as well:

root@maas-xenial2:~# apt policy bcache-tools
bcache-tools:
  Installed: 1.0.8-2ubuntu2~ppa3
  Candidate: 1.0.8-2ubuntu2~ppa3
  Version table:
 *** 1.0.8-2ubuntu2~ppa3 500
        500 http://ppa.launchpad.net/raharper/bugfixes/ubuntu xenial/main amd64 Packages

...
dev.label (empty)
...

root@maas-xenial2:~# cat /etc/udev/rules.d/bcache0.rules.rules
SUBSYSTEM=="block", ACTION=="add|change", ENV{DEVNAME}=="/dev/bcache0", SYMLINK+="disk/by-dname/bcache0"

So, it seems like a dname symlink -> UUID symlink was not created. The /dev/bcache/by-uuid rules are there.

I did try a manual label writing test based on the kernel code - a written label seems to persist after reboot.

So something tells me that I simply did not get the new *curtin* code.

I will poke around more in the morning - any ideas are appreciated.

Also, thx for working on this.
