Re: [Ltib] Where does rootfs/var/lib/rpm and content come from?

[Stuart Hughes]

Hi Peter,

Those files are the rpm database and so don't show up as they are not in 
a package themselves (they're a by-product of all the installed packages).

For NFS deployment those files are always left there.  The purpose is so 
that if you choose to make a disk image, that will have a populated rpm 
database so files can be tracked (and packages removed).

If you have set the deployment type to anything else, you'll see a 
option in --- Target Image Generation / Options -> called:
        (/var/lib/rpm) remove target rpm database
If you do not have the target rpm package selected, it defaults to 
/var/lib/rpm and all the target rootfs/var/lib/rpm files get removed 
when making the image (jffs2, ext2.gz).  If you do have the target rpm 
package selected the the value is "" and the rpm database for the target 
will be left.  Note you can of course override this by manually setting 
it to /var/lib/rpm.

Regards, Stuart
