Do I really need Apparmor to confine Chrome/Chromium-browser? From what I’ve read so far it has its own sandbox mechanism. Ubuntu 11.04 has a ready profile for Chromium-browser and after updating to 11 I find that I can’t open Chromium anymore. Opening the application on a terminal gives me a cryptic message informing me that I don’t have permission for /sys/dbus/pci/devices/** I put the Chromium profile to complain for now. I want to find a more elegant way to secure Chromium after some of my questions are answered. I use Chromium as an alternative browser. Additional issues with Chromium-browser has something to do with me using Xmarks. Xmarks seems to have issues with Google sync and duplicate sync services so I had to disable the Xmarks sync altogether. I thought I had a nice solution to this one a few days ago.
I first encountered the problem after a routine update / upgrade of the
system. Well there was a kernel upgrade and I have not checked how many
old kernels are still left for backups in /boot. Apparently, there was
a few and the partition is 85% full. Every software update included a
warning because of the restriction in disk space. Also, zfs could not
create snapshots. It is also full. This is not very clear to me.
Snapshots were suppose to be diff copies so why would it take up a
large space. Most of the snapshots are less than 2MB. Or 0MB.
Another problem that popped up is the constant freezing of Rhythmbox. I
don't know if the config files are corrupted. The CPU cycles from one
to the next. Peaks for 5-6 seconds then on to the next CPU. This forced
me to download Clementine and Audacious. But both applications do not
find the zfs pool or don't show the zfs structure. Why not? My final
solution is to reinstall Rhythmbox via snaps. I re-scanned the music
