dmesg
dmesg: read kernel buffer failed: Operation not permitted
Userspace scripts (such as used to read pics from cameras & sdcards)
and many progs often use dmesg to detect or identify things like startup
probe info, USB devs, partition numbers etc.
I worked around this by setting the suid bit of `which dmesg`, but it
would be rude to force everybody to manually do this as part of
post-install cleanup.
Hopefully an unintended side-effect and not a new "feature" that
wasn't thought through completely. A web-search suggests debian/ubuntu
may have been doing this for awhile- but we really don't need to be just
like them... ;)
This was intentional and there was a thread about this recently,
probably on devel or test. It's considered to be a big security issue.
If you're in the wheel group, you can use "journalctl -k".
