This adds a separate package for the 2.0 branch of Bird, allowing it to co-exist with the bird1 package. The two packages conflict with each other, so they can't be installed at the same time; but in the build system they coexist just fine. Signed-off-by: Toke Høiland-Jørgensen <toke@toke.dk>

Subject: [PATCH 2/2] Better initialization of random generator
|
|
|
|
Use full time precision to initialize random generator. The old
|
|
code was prone to initialize it to the same values in specific
|
|
circumstances (boot without RTC, multiple VMs starting at once).
