Can you, from the hosts, do a ls -ln on one of the offending
directories and show the results?  Seems there are 3 possiblities,

1. the files are simply chowned to wrong uid altogether
2. the files are chowned to the username rather than uid, and jamie's
   user/group is different between hosts.  That's a bug in lxd, it
   should use the numeric values.  (Probably a missing tar flag)
3. the files are chowned (correctly) to the original uid, but
   the way you're looking at the files uses a different /etc/{passwd,group}
   so the names appear different.
