Hi,
how to check how much space is occupied from the kernel and other stuff. Runninf 'df' gives me:
root:/usr/bin> df
Filesystem 1K-blocks Used Available Use% Mounted on
Best regards,
Nikolay

edit df.c that is in busybox and remove the line where it ignores "rootfs"

Hi Mike,
I found
static const char ignored_mounts[] ALIGN1 =
"rootfs\0";
on this file.
How exactly I have to change it? I tried with empty string, but the result is the same...

that's half the equation. i seem to recall embedded systems have a feature where {ram,tmp}fs filesystems dont actually do accounting. that means you cant stat() to get said information.
you can get a pretty close answer with `du`:
root:/> du -s -h -x /
1.5M
