sysinstall in a jail

[Frederick N. Brier]

I am running into a problem installing packages via sysinstall within a 
jail using the CD media.  I did a minimal install, but added the 
/usr/src directory.  I followed the directions to setup a jail and 
copied /stand/sysinstall into the jail subdirectory.  As per the 
directions, I then started up the jail and ran sysinstall.  But when I 
attempt to install off of the cdrom media, I get the following error: 
"Error mounting /dev/acdoc on /dist: Operation not permitted (1)".  Now 
it makes sense that a jail might not be allowed to mount a system 
device.  My confusion is that these were the instructions and I have not 
seen any posts saying this is a problem.  Is there a way to give the 
jail permission to access the CD device?  Should I mount the CD from the 
host (outside the jail) but to a subdirectory the jail has access to? 
Such as /usr/jail/myjail/dist?  Versus /dist?  Thank you for any 
suggestions.
