Hi,

Good. Debian Policy 3.9.0.0 just hit unstable and apt's "apt-get
build-dep" seems to be fixed. Time to fill bugs and ask maintainers to
remove not+linux-gnu and friends, isn't it?

If so I think I go with the following mail:

|Package & Version & Tag
|Severity: Serious because it breaks armel or just important because we
|          want to get rid of linux-gnu types?
|
|Dear package maintainer, this is mass bug.
|This package uses the keywords linux-gnu, not+linux-gnu or the kfreebsd-
|variant of the former in its depends or architectur field in the
|control file. Please be aware that linux-gnu excludes armel which
|might not be what you want.
|Since Debian Policy 3.9.0.0 architectur wildcards are defined for
|Depends: [0] and Architecture: [1] are defined. You are encouraged to
|start using them. 
|A quick cheat-list for the dependebcy would be:
|"$DEPENDENCY | not+linux-gnu"   =>   "$DEPENDENCY [linux-any]"                                                                             
|"$DEPENDENCY | not+linux"       =>   "$DEPENDENCY [linux-any]"                                                                             
|"$DEPENDENCY | linux-gnu"       =>   "$DEPENDENCY [!linux-any]"                                                                            
|"$DEPENDENCY | linux"           =>   "$DEPENDENCY [!linux-any]"                                                                            
|"$DEPENDENCY | not+hurd"        =>   "$DEPENDENCY [hurd-any]"                                                                              
|"$DEPENDENCY | hurd"            =>   "$DEPENDENCY [!hurd-any]"

|Once no package is using this kind of dependency the relvant keywords
|will be removed from the type-handling package which provides them.

Any comments?

Do you have an example package handy? I'm happy once the linux-any &
friends keywords are gone :)
