Hi Dario, >Just made the first boot :) A small report: > >- previously, we used to add 32Mb to the mfsroot size normally > required. Apparently OpenFirmware didn't like this.

Resolved by removing the exceeding >32Mb. What's happening here is that the mfsroot is overwriting the loader. On the powermac, the loader is placed at 0x1c00000 to try and avoid a conflict with OpenFirmware memory usage (this location was pinched from bootx). So, you're somewhat limited in mfsroot size, since it's placed in memory by the loader directly after the kernel (and before the loader itself). >- usually we extensively use md memory fs union-mounted on compressed > fs for /usr, /var and /root.

Are there still problems with unionfs on recent - currents? Do you get this on -i386 ? Is it possible to isolate this down to a small test case that can be run on a non-FreeSBIE ppc system ? later, Peter.
