su: setting user context: Socket operation on non-socket

THis problem is owner/permision of the files either when pax -pe is not employed or changed after those installation. sysinst added user with uid = 1000, but I've changed to another one, and yet I've wrongly changed some owners. By changing ownership, setuid bit etc will be lost
