<BR><FONT SIZE=2>out of memory? It's usually better to swap over NFS, no matter how</FONT>
<BR><FONT SIZE=2>slow and potentially unreliable it may be, rather than to just OOM.</FONT>

<P><FONT SIZE=2>Yes - absolutely! And as I didn't have any say in how much memory a Dreamcast has/had I cannot really be blamed for only having 16MB.</FONT></P>
<P><FONT SIZE=2>If I use a busybox based shell I have about 10 Megs free. If I use Debian and bash I can have only a few hundred K - hence the need to use swap.</FONT></P>
<P><FONT SIZE=2>So does anyone know how. So far I have tried this:</FONT>
</P>
<P><FONT SIZE=2>dd to make a 32Meg file</FONT>
<BR><FONT SIZE=2>mkswap to turn that into swap</FONT>
<BR><FONT SIZE=2>Edit fstab to put the swap partition in</FONT>
<BR><FONT SIZE=2>and swapon -a to try to mount it - but it fails with a variety of errors</FONT>
</P>
<P><FONT SIZE=2>istr that I need to mount something via loop - as I know someone else has done this (mounted swap via NFS on a Dreamcast) and he did that I am sure - but I cannot contact him at the moment, hence requests for general guidance.</FONT></P>
