Subject: [PATCH] kpatch-build: allow overriding of distro name
|
|
|
|
It is sometimes useful to have ability to override
|
|
distro name, for example during cross-compilation
|
|
build when livepatch modules will be ran on the
|
|
target which differs from host.
|
|
|
|
This patch adds a new --distro option which
|
|
implements all needed functionality
|
|
|
|
Upstream-Status: Pending
