std::filestream::canonical(const std::filesystem::path& p) can throw
exception if the path does not exist. hwmontempsensor would crash with:
what(): filesystem error: cannot make canonical path:
No such file or directory [/sys/class/hwmon/hwmon38/device]
Replace with canonical(const std::filesystem::path& p,
std::error_code& ec) which captures error code without exception.
This call still may throw std::bad_alloc if memory allocation fails.
But there is no good way to resolve system OOM from this service,
leave it unhandled and let the service exit.
Tested:
Same hwmontemp sensors are created with the change.
