 there is a significant number of unowned files on the servers. this is
 generally because a user was removed without the associated user being
 purged as well, but there are also odd corner cases like backup restores
 and so on.

 In #29682, I have done the following Cumin run to find such files,
 expecting to find only problems with the Munin user/group I had just
 removed, but instead found many more cases, mostly (300,000) surrounding
 deleted users:

 {{{
 cumin -p 0 -b 5 --force -o txt '*' 'find / -ignore_readdir_race -path
 /proc -prune -nouser -o -nogroup' | tee unowned-files
 }}}

 Next step is to decide what to do with the leftover files and document
 this as part of the user retirement process.
