I mean the tool can cook the raw error information from kernel and
report it in a better way. Yes. You are right that the user space
error daemon is not popular now. But every tool has its beginning,
isn't it? I know it is impossible for this tool becomes popular in
desktop users because hardware error is really rare for them. But it
may become popular for server farm administrators, to them hardware
errors are common and they really care about the RAS.

I have no objection to report hardware errors in system logs too. So
these people can get the information too. I just want to add another
tool oriented interface too. So that some other users (like cluster
administrator) can get their work done better too.

For desktop users, that is true. But for cluster administrator, the
hardware errors are really common. Some engineer of local search
engine vendor told me that they have broken DIMM everyday.
