I have been moving directories and files between my host and my container
many times since more than one year with no issues. Host is Archlinux and
container Fedora 24 (upgrade to 24 is quite recent: no more than 2 months).
I moved a directory today from host to container and this let me, for the
first time, with a directory in the container owned by 65534:65534.
<The UID 65534 is commonly reserved for *nobody*, a user with no system
privileges, as opposed to an ordinary (i.e., *non-privileged*) user. This
UID is often used for individuals accessing the system remotely via FTP or
HTTP[0] >
>From host, the directory is correctly seen as a root:root
----------------------------------------------
# ls -al
/var/lib/machines/poppy/storage/tth-blog/pelican-themes/material-TTH/static
drwxr-xr-x 1 root root 58 Sep 1 12:10 css/
----------------------------------------------
I can't change owner/group ID from inside the container, which is of course
very annoying as my folders and their contents are unusable.
I didn't change anything in the way my container is mounted:
$ cat /etc/fstab
-------------------------
LABEL=poppy-root /var/lib/machines/poppy
btrfs rw,noatime,autodefrag,compress=lzo,ssd,subvol=rootvol
0 0
---------------------------------
The container is started at boot time with systemd-nspawn at poppy.service
(poppy is the container name)
$ systemctl status systemd-nspawn at poppy.service
