I have debugged this case a bit and found out that
(1) The "/dev/mem: Permission denied" message comes from
/usr/sbin/laptop-detect script which is being executed a few times
during packages installation. Well, in fact the message comes from
dmidecode which laptop-detect calls... Anyway, laptop-detect decides
that we are not on a laptop (which is correct for a container I think)
and exits with the code of 1 (correct in non-laptop case). So it's all
fine, except for the scary error message which you should ignore (and
please do NOT give a container an access to /dev/mem -- BAD BAD idea).
If you want the message to disappear, do this (as root):
rm /usr/sbin/laptop-detect
ln -s /bin/false /usr/sbin/laptop-detect
That way "laptop-detect" is linked to "false" and will always exit with
"1" (meaning "we are not on a laptop").
(2) The "warning: /usr/lib/X11/fonts/misc does not exist or is not a
directory" message comes from xfonts-base post-installation script
(/var/lib/dpkg/info/xfonts-base.postinst) which (aside from tons of
other things) calls these two scripts:
update-fonts-dir --x11r7-layout misc;update-fonts-alias misc
Each script tries to check if a directory named /usr/lib/X11/fonts/misc
-- it does not, and it prints a warning.
I am not sure why there is no /usr/lib/X11/fonts/misc directory but
xfonts-base assumes it's here -- for that, you'd better ask Debian people.
I have also tried to find which packages create the above directory (or
have files in it) and found out nobody's using it. Instead, a number of
packages put some files to /usr/share/fonts/X11/misc.
Executive summary:
1. /dev/mem can and should be ignored.
2. warning about directory is not an OpenVZ issue.
Hope that helps.
