[redhat-lspp] Idenifying Removable Media

[Roe, William H.]

CMW operating systems like trusted solaris prompt the user to identify
the label level of the device or it will assume the label level of the
running process.  Therefore all files copied from that device are given
the that label.

Hi,

A question came up. When media is inserted, there are 3 possibilities if
its
ext3 partition. It could be a plain ext3 partition from a RHEL3 machine,
it could have some SE Linux information from FC3/4, or it could have MLS
information.

How do we identify the media and treat it appropriately so that its not
seen as corrupted by the native machine when the media is returned? From
a LSPP perspective, should extended attributes not be written to plain
ext3 partition? How would someone check it?

This same issue comes up on dual boot machines.

-Steve
