have mounted overlay fs:
overlay on /srv/www/site type overlay (rw,relatime,lowerdir=/srv/www/site_orig,upperdir=/srv/www/site_custom,workdir=/srv/www/overlay_workdir)
I can see and edit files under /srv/www/site, but apache shows that dir is empty. I tried to direct apache's doc root to /srv/www/site, to /srv/www; tried to remove PrivateTmp option from systemd service, but that didn't help.
sudo -u http /srv/www/site
works - I can see the files. (apache runs as http user) Permissions are correct.
doesn't show this mount
