Bug ID: 230876
Summary: save-entropy: Sync saved random data
Product: Base System
Version: CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: bin
Assignee: [email protected]
Reporter: [email protected]
libexec/save-entropy/save-entropy.sh should probably fsync the directory it
modifies as well as the new file it creates to ensure newly saved entropy makes
it to disk in the event of a crash.
(The entire point of save-entropy is to make saved-entropy RNG seeding
crash-resistant — otherwise we could just rely on rc.d/random's shutdown
component.)
