Make kernlog available to product and vendor Bug: 270690570 Test: mma in external/rust/crates Change-Id: I127442bb28b2be55ca928199a25657874d5c36d6
Logger implementation for low level kernel log (using /dev/kmsg)
Usually intended for low level implementations, like systemd generators, which have to use /dev/kmsg:
Since syslog is not available (see above) write log messages to /dev/kmsg instead.
[dependencies] log = "0.4" kernlog = "0.3"
#[macro_use] extern crate log; extern crate kernlog; fn main() { kernlog::init().unwrap(); warn!("something strange happened"); }
Note you have to have permissions to write to /dev/kmsg, which normal users (not root) usually don't.
