Insmod

Hi there friends
I have a problem with this command: "insmod"
When I use it in this order for increasing the size of ramdisk in
linux(FC7 or FC8) the OS prints man page for me:
Help me please any say me how can I increase the size of ramdisk
without editing grub.conf or lilo.conf or compiling the kernel.

OR please explain this:
# insmod rd rd_size=32000

tanx a lot.

"install module" called "rd" with parameter setting ramdisk size to 32MB. BTW, isn't "rd" old? Why not use "tmpfs"?

Add this line (for compatibility with other tools respect how tabs or spaces are used in fstab) "none /dev/shm tmpfs size=32m 0 0" to /etc/fstab, then 'mount -a' (lazy way), then check with 'mount' and you should have a ramdisk of 32MB. How does it work? Copy some files to it and make a tarball of it: 'cp -r /etc/rc.d /dev/shm; tar -vcjf /tmp/rcd.tar.bz2 && rm -rf /dev/shm/rc.d'. You see, it works just like a filesystem.
