Currently, the way scap3 is configured, you cannot deploy from any directory other than a directory that is under /srv/deployment; however, since on deployment-bastion /srv is actually a symlink to /mnt/srv this check fails.
The purpose of this check is to make sure that the git_repo code from the git_server (which is typically tin) is accessible over the network. Since this is enforced in other places throughout the code, this check should be removed.
