Re: [PATCH RFC 0/5] Containerize syslog

Glauber Costa [off-list ref] writes:

I keep asking myself if it isn't the case of forwarding to a container
all messages printed in process context. That will obviously exclude all
messages resulting from kthreads - that will always be in the initial
namespace anyway, interrupts, etc. There is no harm, for instance, in
delivering the same message twice: one to the container, and the other
to the host system.

Except that there is harm in double printing.  One of the better
justifications for doing something with the kernel log is that it is
possible to overflow the kernel log with operations performed
exclusively in a container.

I do think the idea of process context printks going to the current
container one worth playing with.
