Re: Linux Router KIT

[dirk () power net]

I just looked at their site. 

Difference is that they are constrained by having to to fit everything
into 2MBytes.

Ours don't have that limitation. The box that I'm using right now loads
a 20MByte compressed RAMdisk from the CD. I also have /usr on the CD.
When running this looks like this:

sh# df
Filesystem         1024-blocks  Used Available Capacity Mounted on
/dev/ram0              58087   37066    21021     64%   /
/dev/hdc              536232  536232        0    100%   /cdrom
