Re: [Xen-devel] Re: [Xen-users] directing xm dmesg to syslog
Hi, Minai
I think this is cool tool!
I want you to add xenlogd into /etc/init.d/xend.
And I have small comments.
See the below.

You should add -Werror -g option into CFLAGS
And you must add .PHONY, build, install section,
because of "make tools" and "make install-tools"
So you may add "SUBDIRS-y += xenlogd" into tools/Makefile

And STARTMSG isn't used. :-)
This xenlog tools clear a reading part of console buffer.
I think xenlogd which don't clear the buffer is more cool.
But this fix might modify xen's code.
So this fix is trade off.
Hmm....
I hope other comments from community. :-)
