/usr/etc/defaults/useradd has strange permissions

Host system details

Provide the output of rpm-ostree status.

I don't think my host system is relevant right now, but will update if required.

$rpm-ostree --version
rpm-ostree:
 Version: '2019.1'
 Git: 46df99edaf65ee0f3fdf55b441caaaad19c1612d
 Features:
  - compose
  - rust

Expected vs actual behavior

$ ls -lh /usr/etc/default/useradd 
--w----r-T. 4 root root 123 Jan  1  1970 /usr/etc/default/useradd
$ stat -c "%a %n" /usr/etc/default/useradd 
1204 /usr/etc/default/useradd

Expected:

$ ls -lh /usr/etc/default/useradd 
-rw-r--r--. 4 root root 123 Jan  1  1970 /usr/etc/default/useradd
$ stat -c "%a %n" /usr/etc/default/useradd 
0644 /usr/etc/default/useradd

Interestingly 1204 in octal is 644 in decimal.

In fairness my use-case if fairly niche - I need to be able to read (to checksum) all the files in a ostree checkout when running as non-root. Using ostree checkout -U --repo=$repo $ref I end up with a file that my user cannot read from.

Steps to reproduce it

This seems to be with any image generated since #1726

Would you like to work on the issue?

I don't think I have the expertise to work on this!

Sorry about that; PR in #1753

Thanks! I had to look up how to do octals in rust too
