I had to abort a backup of my system because it stalled on the file
/proc/kcore. I check its size and, well, the file is enormous. Checking Google, it seems that many other people have absurdly large kcore files as well.
I have three questions:
- should I be concerned about kcore's size?
- if so, how can I reduce its size?
- is there any reason to backup the /proc/ directory?
