%general-entities; ]> /etc/fstab boot The /etc/fstab file is used by some programs to determine where file systems are to be mounted by default, which must be checked, and in which order. Create a new file systems table like this: cat > ${CLFS}/etc/fstab << "EOF" # Begin /etc/fstab # file system mount-point type options dump fsck # order /dev/[xxx] / [fff] defaults 1 1 /dev/[yyy] swap swap pri=1 0 0 devpts /dev/pts devpts gid=&gid-tty;,mode=620 0 0 shm /dev/shm tmpfs defaults 0 0 # End /etc/fstab EOF The /dev/shm mount point for tmpfs is included to allow enabling POSIX-shared memory. The kernel must have the required support built into it for this to work (more about this is in the next section). Please note that very little software currently uses POSIX-shared memory. Therefore, consider the /dev/shm mount point optional. For more information, see Documentation/filesystems/tmpfs.txt in the kernel source tree.
