config BR2_PACKAGE_EMLOG bool "emlog" depends on BR2_LINUX_KERNEL help emlog is a Linux kernel module that makes it easy to access the most recent (and only the most recent) output from a process. It works just like "tail -f" on a log file, except that the storage required never grows. This can be useful in embedded systems where there isn't enough memory or disk space for keeping complete log files, but the most recent debugging messages are sometimes needed (e.g., after an error is observed). https://github.com/nicupavel/emlog comment "emlog needs a Linux kernel to be built" depends on !BR2_LINUX_KERNEL
