I'm currently working on compiling GCC 3.0.4 on my Indigo, and the default value of ncargs is too small at a certain point during the process. I messed around a bit and was able to figure out how to increase it (4.0.5 has no `systune`).

Line 256 of `/usr/sysgen/master.d/kernel` should be
Code:
#define SYSNCARGS       (10*1024)       /* wastes stack space if too large */
by default. I changed `10*1024` to `50*1024` and that worked successfully.

After you make this change, run `autoconfig` to generate a new kernel. Once you reboot, the new ncargs value should be in effect.

AFAIK it isn't any different now either, the default is just way larger. Looks like the Linux on my laptop could execute a command line of ~2 megabytes.
