edit a file /etc/fstab , what parameters can be changebale and which parameters
Hi guys,
I can't find any detail explanation which parameters on /etc/fstab file I can change and not cause critical errors for system. Which values they can get.
After i change some parameters I stuck after reboot system on "Emergency-mode" and sometimes system changed to red-only.
If you provide specific information as to what settings you have attempted to change and what you wish to accomplish, perhaps more precise responses could be provided.
When I edit /etc/fstab, I commonly comment out the line I intend to change and create a new line with the changes I wish to make. That way, I can quickly restore the original line if I break something.
Can you please post the contents of your /etc/fstab here. That will allow us to better answer your question.

Can you try setting <pass> to 1 for / and 2 for /boot. Leave it as 0 for the swap partition, and leave all the <dump>s as 0 (assuming you're not using the dump utility).
Let us know what happens.
As a side question, are you using Grub? If so, after you've rebooted, can you run update-grub as root and paste the output here?
