I can just delete this junk, right? I uninstalled prelink a week ago. All the original files (such as /usr/bin/fcatch) still exist. grep prelink notinrpm|xargs ls -la -rwx------ 1 root root 1167392 Nov 8 00:16 /usr/bin/fcatch.#prelink#.mR0Mh4 -rwx------ 1 root root 432048 Oct 25 14:57 /usr/lib/libGL.so.1.2.#prelink#.4d5NTW -rwx------ 1 root root 432048 Nov 7 15:49 /usr/lib/libGL.so.1.2.#prelink#.CrNzAV -rwx------ 1 root root 432048 Nov 10 13:19 /usr/lib/libGL.so.1.2.#prelink#.EVfsl4 -rwx------ 1 root root 432048 Nov 4 11:51 /usr/lib/libGL.so.1.2.#prelink#.OzfHpZ -rwx------ 1 root root 432048 Oct 29 11:06 /usr/lib/libGL.so.1.2.#prelink#.uD3o9v -rwx------ 1 root root 453800 Nov 10 13:16 /usr/lib/libSDL-1.2.so.0.11.0.#prelink#.9EEnah -rwx------ 1 root root 453800 Oct 29 11:15 /usr/lib/libSDL-1.2.so.0.11.0.#prelink#.oaoGxQ -rwx------ 1 root root 453800 Nov 4 10:45 /usr/lib/libSDL-1.2.so.0.11.0.#prelink#.R0uV2b Thanks, Dave
