Description Robert Buchholz (RETIRED) gentoo-dev

2007-11-29 20:29:57 UTC

in 2.6.x and 2.4.x kernels, if a core file owned by a non root user exists and 
root runs a process that drops core in the same location, the original core 
file owned by the non root user is replaced with root's core dump, except the 
original owner maintains ownership of the core.
