Boot to RAM

[Danishka Navin]

Hi there,

Does anyone boot a Fedora server or workstation in to RAM?
I mean an installed system.
Btw, I need to keep persistence data in specific directories.

Regards,

You need to provide more detail about what you're wanting to do.  How is 
this different from a live boot?

its about running moodle on fedora where around 50 users connect via local
network.
it has higher disk writes compared to reads when user move from one page to
another (it keep track of user actions in the db).
either LiveUSB or LiveDVD smoothly working but installed USB won't work
(gateway timeouts when we use installed USB).

My idea is to make the installed USB boot in away entire system load in to
memory but I need to keep persistence data in  /var/lib/mysql and /var/www/

Sounds like you want something similar to Pi builds:

May be a good spring board?

You probably just need to determine where the temp data is going and
put a tmpfs mount in that location so it uses ram for the temporary
files you don't need to keep.

Any static files that are only being read from the usb device on boot
up will quickly get cached into ram assuming you have enough ram.
