commit 764780294f1df220174c1eb2208c0774d685d594 Author: Warner Losh <[email protected]> AuthorDate: 2022-06-30 18:12:51 +0000 Commit: Warner Losh <[email protected]> CommitDate: 2022-07-15 18:00:50 +0000 kboot: Implement getpid(2) Add host_getpid() so we can know if we're running as init(8) or not. If we are, we may chose to do early system setup / sanity operations.
