Points to ponder:
If a package depended on "ABI XYZ", which is provided by
"kernel XYZ", would it be allowed to use features specific
to "XYZ" in preinst and postinst routines?
In my opinion yes. At least assume yes for now.
Then that would mean you can't install this package unless
you had that kernel booted up...
So perhaps for (a) there should be the rule that you can only
download for the currently booted kernel?
Not a very satisfactory solution though :-(
As for installing a hurd package at the same time as a Linux
package, I think there are several options (warning: stupid
options also listed):
- Store both in a separate directory, and set path accordingly.
Probably break the FHS in the process.
- Store both is separate directory, and use chroot environment
depending on platform. This wont allow sharing files.
- Have the kernel redirect requests at run time. This would work
for Hurd, but not for Linux.
- Have the hurd package conflict with the Linux package. Doing
anything else would require dpkg support installing different
versions of the same package? I tend to favour this option
myself, especially if Hurd can ever run Linux binary files.
- any other options I might have missed?
