Previously, even when writing e.g. /etc/hostname fails, the static hostname in Context is not restored. So, the subsequent call of the same method succeeds: ``` $ sudo chattr +i /etc/hostname $ sudo hostnamectl --static set-hostname aaa Could not set static hostname: Access denied $ echo $? 1 $ sudo hostnamectl --static set-hostname aaa $ echo $? 0 ``` This makes when updating file is failed, the saved stat is cleared. So, the static hostname or machine information in the context are always consistent to the corresponding files.
