It seems you have some error messages: "
system/mountroot : bash_helper[system/mountroot]: line 16: /usr/bin/awk: No such
system/mountroot : file or directory
system/mountroot : bash_helper[system/mountroot]: line 16: /usr/bin/sort: No such
system/mountroot : file or directory

"
Here in my system, mountroot.i does not seem to contain references to awk. But in general, my mountroot.i references files like mount, grep and rm as /bin/mount, /bin/grep and /bin/rm. In my system, these files are in /bin, not /usr/bin. Sometimes there is a symlink in /usr/bin to the real file in /bin.
So why is your mountroot.i calling files in /usr/bin? And why is your mountroot.i using complete path anyway?
Anyway, if you want to get rid of these errors, I think you should upgrade your ifiles. I'm using the ones from CVS.
