Chen,
You NEVER EVER want to include /proc, /sys, /tmp, /media, /dev in your
backup/iso. They're not really files but points to other systems data,
or your kernel's internal structures.
If you're on a 64bit machines, then yes - the "virtual" size of these
files can be quite large. That's normal. They're not meant to be
written/read by normal processes. So simply exclude the non persistent
mount points, temporary and "cd/usb" mount points when you do a system
dump like that.

Stupid nick highlighting
Whenever someone starts with "stupid" it highlights the nick. Hmm.

Hi,
I am running Fedora 13 with the 2.6.33.5-112-2.2 kernel, and am trying
to make an ISO image of my hard disk for other use. Unfortunately
“mkisofs” failed because /proc/kcore exceeded its 4GB file size limit.
In fact, the size of the kcore on my system is shown to be 128TB, and
the machine itself only contains 2GB of RAM. Has anyone experienced
the same problem? BTW, the kcore files on my redhat machines reflect
the actual RAM size as it should be. Also, does anyone know why
“mkisofs” even tries to copy a virtual file into the ISO image it is
creating?
Thanks,
H Chen
