[Buildroot] Anyone know how I can make my Buildroot filesystem R/W?

[Arun Reddy]

I am so happy that I have my new bootable filesystem created by buildroot!
But I noticed when I boot it up I can't write or change anything. Does
anyone know how I can make my new system R/W instead of just R?

Thanks for the help!

you need something more than 'mount -o remount,rw /'?

[Buildroot] Anyone know how I can make my Buildroot filesystem R/W?

Sean,

I did find this option as well looking online, but where must I enter it? I
know this must be a trivial question but I can't figure out how to make use
of it.

Thanks!

Hi Arun,

?Have a look in the manpage for mount. Just a trivial 'man mount' in the
command line. Then you will stumble across the syntax and options etc.
and you finally realize you have to type 'mount -o remount,rw /' in the
shell of your bootable filesystem. Thus your FS will be remounted with
the rw options.

Best regards

Emil,

Thank you. You are correct the man pages would have helped me solve this
problem quickly. I will make sure I use that resource quickly next time!

BTW I've ported unionfs to buildroot; that allows to keep the root read-only, 
and make any number of changes on a root file system that appears as 
read-write. You can put the read-write delta on a small partition on a SD 
card or something... Easy to backup, easy to revert, easy to upgrade...
