To me this is like saying 'move everything into /usr but because its volitile move it back into /var but in a sub-directory from where it was so you can keep an image running.' In this case, this doesn't sound like any savings and more of a headache of why did it corrupt this time. Looking at my /var/lib in F35, the __db.*** files seems to get written to regularly but I am not sure why. That would probably be something to track down and remove from images afterwards. > Moreover, for systems where /usr is read-only and/or shared (especially > stateless systems), having the rpmdb on /usr seems like the most > rational place for it, if one expects to be able to use rpm to query the > package list.
