[Buildroot] big root fs

[Zoran Djordjevic]

By the way, what is your opinion about putting root FS on SD 
card. Does it slow the system down, or have some other 
missadvantages, other then pulling the card out accidentally?
 
Regards

As Avery said, look around with du and ls in your filesystem to check
where the size is, and whether or not the biggest things are actually
useful or not.

Alternatively, could you put online a tarball version of your
filesystem, so that others could help you pointing what are the
problems?
