Usually less than 24 hours but there is a libpng security update that hasnt been taken care of im guessing because its been 3 days since the posting on redhats site..

i have checked all the mirrors listed on the site (centOS) and yet to see the updated libpng rpm...

i understand that kernel issues are some what different in being that it deals with pretty much the whole system..but...

a libpng update is something rather small and could have been released already...i have rebuilt the src.rpm on a test server (using rpmbuild --rebuild src.rpm) but didnt know exactly if that was the proper way to rebuild the src rpms (if thats how the people at centOS do those) and didnt install it on my production server...and if it is that easy then i could just rebuild the src.rpms that dont need any spec file changes until i get a better understanding of what needs to be changed in those type of situations..and just wait for kernel updates from the people at centOS themselves to rebuild those(kernel updates)

i am using up2date to keep my system updated with the necessary updates from the servers...could that be an issue or not?

i have no problem rebuilding the src.rpms if how i do it is the proper and correct way to accomplish such a task..
