For FC6 we're looking at bringing forward and integrating some of the
Stateless Linux work. More detail will be up at:
http://fedoraproject.org/wiki/StatelessLinux
although probably not for a couple of days.
One of the main tenets of this is that the system filesystems should
be able to run read-only; there's no reason for apps to be writing
to the system filesystem in general use. However, tracking this
can be difficult; you don't want to force everyone to run read-only
just to get data on their workloads.
So, what we've worked on is a way to simply log what apps are writing
to (or trying to write to) the system filesystems. This is now
available at:
http://people.redhat.com/notting/rolo/
A readme for this is attached. Basically, we're interested in getting
logs from a variety of workloads, ranging from basic desktop to server;
with this information, we can make sure that a readonly root scenario
works for the majority of use cases that someone might want.
Right now, reports can go to this list, in this thread or similar.
If we need to set up a separate mechanism for recieving them, we
can.
