DESCRIPTION="Kernel module for dev-util/sysdig"
|
|
HOMEPAGE="https://sysdig.com/"
|
|
|
|
# The driver is part of falcosecurity/libs, but for versioning reasons we cannot (yet)
|
|
# use semver-released packages; instead we pull in a commit that is used and known
|
|
# to work with sysdig, see sysdig/cmake/modules/falcosecurity-libs.cmake for details.
|
|
# For now the commit here and the one referenced in sysdig should be in sync.
