After a fresh install of Linux, there are a number of tasks I like to do. I like having commands and aliases that I am used to installed.
set up MySQL
Install WebMin and VirtualMin for managing your domain names and their.
In Linux, there are times when you need to edit your /etc/fstab file to add a new disk. Sometimes, you may accidentally edit the wrong information which will cause Linux to not boot. Usually though, Linux plays nice and boots to a command prompt. Unfortunately, you are now booted into a read-only filesystem so you are unable to save your /etc/fstab.
What you need to do is first set the operating system to read/write (r/w). To do this run the following command:
>mount -o remount,rw /
If /etc is on a different volume, then run this command (replace /dev/sda1 with your /etc volume):
>mount -t ext3 /dev/sda1 / -o remount,rw
Some people have complained about kernels that are not compiled to support the reldiratime option. If you are still having trouble editing and saving /etc/fstab, try this:
>mount -o remount,defaults /
You should now be able to edit and save your /etc/fstab file and reboot and have Linux back again!
