How to use a ramdisk?
The HOWTOs talk about ramdisks as part of the install process, but not
as something I can use every day. Assuming that I *can* have a ramdisk
on hamm, how do I set it up?
So far, I've:
put 'ramdisk=2000' in my /etc/lilo.conf file (and run lilo). dmesg tells
me that 16 2000K ramdisks were set up, but free shows that no memory is
consumed so I assume there's another step to making them available.
I want only one, BTW. :-)
What's next? I'd expect to need to put something in /etc/fstab, but
what's the device file? (/dev/ramdisk?) What if I want more than one?
And what's the expected/traditional mount point? The fstype? Is
there any further configuration to be done?
How do I use ramdisks once they're created? Just copy my files to the
disk and symlink to them from where they're expected to be? What do I
do to ensure that the files are written to (real) disk on shutdown or
at predefined intervals?
I'm so full of questions. Surely there's documentation on this
somewhere. But: Where?
Thanks,
