Can anyone guess, why duplicity suddenly started to make or treat the first hostname letter uppercase?
[root@crew shared_scripts]# duplicity --version
duplicity 0.7.10
[root@crew shared_scripts]# uname -a
Linux crew.gdndev.xyz 3.10.0-327.28.3.el7.x86_64 #1 SMP Thu Aug 18 19:05:49 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
[root@crew shared_scripts]# echo $HOSTNAME
crew.gdndev.xyz
[root@crew shared_scripts]# hostname
crew.gdndev.xyz
[root@crew shared_scripts]# duplicity --archive-dir /archive-dir --name backup-name --no-encryption --full-if-older-than 2W /backup-source scp://backup-destination

Fatal Error: Backup source host has changed.
Current hostname: Crew.gdndev.xyz
Previous hostname: crew.gdndev.xyz
It was OK yesterday... No package updates for over a week. Uptime 6 days.
What are other ways to get hostname, some other source? Something which could be altered and not affect $(hostname)?
