Apt.installedBackport would do this:
apt-get install -t stretch-backports foo bar
Apt.backportInstalled does this:
apt-get install foo/stretch-backports bar/stretch-backports
The Apt.installedBackport behaviour can install the dependencies of foo and bar
from stretch-backports even when the versions in stretch will satisfy the
dependencies of the backports of foo and bar. So this property can result in
very many more backports being installed on the host when intended. But the
number of installed backports should always be minimised.
Worse, whether this happens is highly dependent on the system state, and the
order in which other properties get ensured. For example,
& Apt.installed ["dgit"]
& Apt.installedBackport ["dgit"]
will install only dgit from stretch-backports, but unless debhelper and
devscripts happen to already be installed,
& Apt.installedBackport ["dgit"]
& Apt.installed ["dgit"]
will install dgit, debhelper, devscripts and maybe more from backports. This is
surprising, difficult to debug, and breaks the expectation that when the order
in which properties are ensured is not specified with connectives like
`requires` and `before`, ensuring them in any order will produce the same
result.
Property renamed because user configs should not silently break, as they would
if they did not list dependencies that must be installed from stable-backports.

which seems to not work anymore.
Thanks, Russell Sim.

getInstallStatus returns [] when passed only such packages,
and all of that list == IsInstalled. So also check that the list contains
every package queried.

It is probably best to use Apt.proxy for this.

the default CDN.
This info is used by Apt.stdSourcesList and Sbuild.builtFor.
Thanks, Sean Whitton.

Though stdArchiveLines is not used in Apt.hs, this is the logical replacement
for the old debCdn property.

* Added Monoid instances for Property and RevertableProperty.
* Removed applyToList. Instead, use mconcat. (API change)
Eg, if you had: applyToList accountFor [User "joey", User "root"]
use instead: mconcat (map accountFor [User "joey", User "root"])
mappend x y is basically the same as x `before` y. In particular, if x
fails to be ensured, it won't ensure y. This seems to make sense, since
applyToList had that behavior, and so does the Monoid for Propellor
Result. The alternative would be to try to ensure both and combine
the results. However, I don't see any reason to do it that way.
It would be nice if the description of both properties were displayed when
ensuring the combination. But then, it would need to display eg:
ensuring x..ok
ensuring y..failed
ensuring x and ensuring y..failed
Without a way to get rid of that redundant last line, I don't want to do
that.
Note that the haddocks for the Monoid instances need a really wide screen
to display! This is IMHO an infelicity in haddock, and I can't do anything
about it really.

* Apt: Removed the mirrors.kernel.org line from stdSourcesList etc.
The mirror CDN has a new implementation that should avoid the problems
with httpredir that made an extra mirror sometimes be needed.
* Switch Debian CDN address to deb.debian.org.
httpredir.debian.org points to the same IPs as deb.debian.org now, so
this shouldn't change anything except to use the now preferred name.

This reads much better: it's an "apt package preference".
