Setting up Fedora 18 for an SSD

Just some short points on setting up Fedora 18 or for that matter probably most Linux flavours for an SSD.

I've highlighted the bits I changed:

/etc/fstab changes:

• /dev/sda   /   ext4   noatime,nodiratime,discard,errors=remount-ro 0 1
• tmpfs   /tmp       tmpfs   defaults,noatime,mode=1777   0  0
• tmpfs   /var/spool tmpfs   defaults,noatime,mode=1777   0  0
• tmpfs   /var/tmp   tmpfs   defaults,noatime,mode=1777   0  0
• tmpfs   /var/log   tmpfs   defaults,noatime,mode=0755   0  0 (only do this if you don't care about loosing logs on reboot!)

/etc/default/grub changes:

• GRUB_CMDLINE_LINUX_DEFAULT="quiet splash elevator=deadline" add the elevator bit to the end.
• grub2-mkconfig -o /boot/grub2/grub.cfg

Chrome to use its cache directory as the tmp director, which is in memory already add the following to the shortcut.

• --disk-cache-dir="/tmp" --disk-cache-size=104857600
