Industy PC with linux

[bluesheet]

Dear all,
I want to build a industy PC with linux, I want to ask a question, can I make a linux system to be read only, how can do it? Can anyone give me some tips!

In my plan,
/ will be readonly
/etc will be read-write
/root will be read-write

can I do it. Thanks.

You are asking about file permissions. Yes you can do what you described, easily. Look at the "Linux File Permissions" tutorial by GoldenEye.

if you want a directory and everything under it to be read only the easiest way would be to create it's own partiition and mount it read only

I think

#  chmod -R 744 directory_name

would probably be easier than repartitioning.

lol true, just offering an alternative which can be reverted back to normal setup easily without having to worry about original permissions
