Use aptly repo include

This can be used to replace aptly publish repo ....

[freeyoung]

apt repo include could detect distribution from .changes file, so the script dput2aptly can be replaced with apt repo include ... && apt publish update ....

Example of .dput.cf:

[dest]
fqdn = deb.yourserver.tld
method = rsync
login = username
incoming = /home/username/.aptly/incoming
pre_upload_command = ssh %(login)s@%(fqdn)s mkdir -p %(incoming)s
post_upload_command = ssh %(login)s@%(fqdn)s "aptly repo include %(incoming)s && aptly publish update %(dest)s"

Then your dput command could be:

dput dest:trusty package.changes
