Ramdisk on standard Ubuntu

[Headworx]

Hi,

To reduce flash wear, I would like to set up a ramdisk to hold temporary webcam images, that are continuously uploaded by a web camera. Can anybody please point me to a solution...? I am new to Linux... Found some how-to's on other boards, but they all refer to grub which is not present on the Sheeva...

Cheers,

Code:

mkdir /media/ramdisk
mount -t tmpfs tmpfs /media/ramdisk

most likely /tmp is already a tmpfs. Check with

Code:

mount |grep tmpfs

Thanks, but I am getting mount: unknown filesystem type 'tempfs'

Cheers,

no E in tmpfs

sure it does work now... i need a bigger screen I guess... now one last thing... I need to put the mounting code somewhere in a startup script... there are a lot of them in /etc/init.d... which is the right one?

Cheers,

A suitable entry in /etc/fstab should get it done automatically for you.

Note also that /var/run seems to be mounted as tmpfs automatically during startup for me, and if so maybe you could (ab)use that instead?  It's all the same storage.

so how does a suitable entry look like in thsi case....? my fstab is just:

# UNCONFIGURED FSTAB FOR BASE SYSTEM

I'd rather have a separate mount point below /var/www, as I need the ramdisk for temporary image uploads... Would not want to mix that with /var/run...

Mine looks like this:

Code:

# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>       <dump>  <pass>
/dev/sda1         /usb           ext4    defaults        0       0
/usb/swap.img   none   swap   sw   0   0
tmpfs /tmp tmpfs defaults,noexec,nosuid 0 0
