Subject: [PATCH 12/50] kata-runtime: truncate the log.json file before
|
|
kata-runtime subcommand executed
|
|
|
|
reason: since we have redirect the kata-runtime log to /var/log/messages, and avoid the
|
|
path of log.json file to be large in the tmpfs, so we truncate the log.json file every
|
|
time before subcommand is executed.
