When I do umount /mnt I see only 2 Gb used memory again. If I play 2-3 movies of 5 Gb each size then tmpfs goes to the end of RAM! So I figured out that the /dev/sda1 is now a part of my root file system and if I read any file from it this file is "putting" on tmpfs!

While playing the movie I can see the amount of used memory is growing and growing and when the movie is ending I see 7 Gb are used! Only 2 Gb were used before playing. My root partition is about 2 Gb, so it uses about 2 Gb of RAM and 14 Gb are free.īefore this I started the command "top" in my terminal emulator. It's very good manual, I tried it and got success.īut I have found very horrible, terrible thing! I tried edit initrd/scripts/local, but I had the same results. The system boot correctly, but my rootfs did not changed, it always in NFS instead to become RAM.

Every file will be loaded to RAM ! A fresh install uses about 2 GB auf harddisk-space.Ĭp /etc/fstab /etc/fstab.bak* find the line specifing the root partition and change it in:Ĭd /usr/share/initramfs-tools/scripts/* make a backup of /usr/share/initramfs-tools/scripts/localĬp local local.bak* modify local, find this line:

).īoot your new system, install updates, drivers if neccessary (this will improve performance), strip it down to the minimum. Make sure you split it into multiple partitions (/, /boot, /home, swap. * mkinitramfs or a tool to build a new initramfsĬhoose a distribution thats supports booting from initramfs. * Debian based distribution or any that supports booting from initramfs
Since this is a virtual filesystem in RAM, not a virtual harddisk, this has many advantages. This will only work with Debian 5 or newer and Ubuntu 9 ? or any unix thats supports booting from a initramfs.

Milomak, could you help me understand the commands in the lines we are adding to the menu.lst file please? That is, what would be the lines that we have to add to the menu.lst file?
