inird: http://www.ibm.com/developerworks/linux/library/l-initrd.html http://en.wikipedia.org/wiki/Initrd ramdisk: http://www.vanemery.com/Linux/Ramdisk/ramdisk.html In recent times, ramdisk in the context of an initrd is really a misnomer and is more accurately an "initramfs" - cpio archive that is extracted into a tmpfs on boot. Earlier, initrds used to images that could be loopback mounted. Same effect except that the tmpfs method doesn't need a filesystem driver. A RAM disk is a device in /dev/ram* that shares a dedicated portion of your RAM and can be configured with a kernel parameter ramdisk_size. Unlike a tmpfs, this memory is not swappable and can't be shared by the kernel. -Joel On 12/16/09, Daniel (Youngwhan) Song <breadncup@xxxxxxxxx> wrote: > Hi, > > initrd is also RAM disk, then what is major difference between initrd and > regular RAM disk? > > Best Regards, > Daniel (Youngwhan) Song > -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
