Will rfs change when kernel image is built(for a target board)


Hi,

Will root file system built for a kernel get changed while building image for that kernel after modifying the configuration.(for target board)

Also if it changes, what will happen if we continue to use the old root file system for the new kernel image.

Thanks in advance,

In general, it does not get modified. There are special cases, however, when you can change it. If you no longer support the filesystem your / is in the new kernel, for instance, you can run into trouble, so check that carefully.

Hi,

I understand only the first sentence in your reply.

I have this doubt coz im using the same root file system even if i modify the kernel configuration and use the new image.

It works !
But have doubt if it will have any impact?

Thanks & Cheers,

I'll try to explain

Your root filesystem is of some type: ext3, xfs or a different one. If your new kernel has support for the right filesystem, everything should be fine. When you forget to include the support, or add support for a different version of the same filesystem (it's rarely possible, but still), it may not work.

In general, there may be differences in the way different kernels handle the same filesystem, but they are rather invisible for the user.
