Wait until a path exists
waitfor pathname [wait_time]
Neutrino
The waitfor utility pauses temporarily until a stat() on the specified pathname succeeds. It's often used for synchronization, to allow a resource manager to perform its startup functionality, and then for the process manager to proceed with the further interpretation of the script file.
Native io-pkt and ported NetBSD drivers don't put entries into the /dev/io-net namespace, so a waitfor command for such an entry won't work properly in buildfiles or scripts. Use if_up -p instead; for example, instead of waitfor /dev/io-net/en0, use if_up -p en0. |
