Hi, just out of curiosity: Within a kickstart postinstall script, I tried to do a loop mount, which failed. It turns out that there is no /dev/loop0 (no /dev/loop<x>). After creating it with mknod /dev/loop0 b 7 0 everything works fine. Now this script executes in the chroot system. This is the system on the hd. A plain chroot system should not have any /dev or /proc mounted. But actually, it does: + cat /proc/mounts rootfs / rootfs rw 0 0 /proc /proc proc rw 0 0 /dev /dev tmpfs rw 0 0 /dev/pts /dev/pts devpts rw 0 0 /sys /sys sysfs rw 0 0 none /tmp ramfs rw 0 0 none /tmp/ramfs ramfs rw 0 0 /proc/bus/usb /proc/bus/usb usbfs rw 0 0 /tmp/loop0 /mnt/runtime squashfs ro 0 0 /tmp/sda1 / ext3 rw,data=ordered 0 0 /tmp/sda3 /home ext3 rw,data=ordered 0 0 /tmp/sys /sys sysfs rw 0 0 /tmp/proc /proc proc rw 0 0 /dev /dev tmpfs rw 0 0 So I assume that centos kindly does a bind mount of these pseudofilesystems (?) from the install system for me, so that the chroot system is a fully functional system. (Is that true?). If that is so, why is there no /dev/loop0? Isaac
