$ rpm -q libsolv
libsolv-0.6.11-1.fc22.x86_64

Sounds great ...

Right now only AND and OR is supported by libsolv. Implementation of IF
ELSE is still pending.

Also we still need to settle to a final syntax for the operators [1].
Unfortunately there is no consensus among the other packaging formats
what to use. Right now rpm accepts 3 different styles:
 * AND OR IF ELSE
 * & | ? :
 * && || ? :
But the final release will only support on of them. As soon as the alpha
stops eating babies that's a discussion we need to have.

So for now they are more a tech preview in Fedora but we want to get
them operational til the release.

Never thought about anything else than Rawhide ...

This still means that they are not
supposed to be used in F23 as they may only completely work very late.
Also there is still a lot of paper work to do for the packaging policy.

I expect that both Boolean Deps and File Triggers won't be introduced in
one go but there will be multiple Fedora Features introducing them one
use case at a time. E.g. one feature per file trigger replacing one kind
of scriptlets. Boolean dependencies being used for language packs being
one Feature/Package Policy section and other use cases being others.

Just out of curiosity, do you have already any candidates for File Triggers? I suppose "/sbin/ldconfig" is one of them. Do you plan to have some F24 feature to get rid of these?

This may start in the F24 time frame - especially for some urgent corner
cases - but my guess is that this will rather take multiple releases.

​Is there a reason why we can't maintain all three kinds? Also, why in the world are bitwise operation operators supported for logical operations? I'd be okay with maintaining options 1 and 3, to be honest. ​

1 and 3 looks good to me.
