Subject: [PATCH 2/2] make version check optional
|
|
|
|
cf. Github PR#86
|
|
|
|
Rather than using an LSM such as SELinux to limit network access, or
|
|
having to add exceptions into network monitoring, allow lshw to be built
|
|
so that it doesn't do the DNS lookup to check for upstream version
|
|
updates.
