|
| Maybe. I have a script that will effectively do a installsmallworld
| target. The guts of the script are a for loop that does
|
| (cd $FreeBSDSrcDir
| make -m ${FreeBSDSrcDir}/share/mk -f Makefile.inc1 \
| hierarchy DESTDIR=$1 NOMAN=yes
| (cd etc ; make -m ${FreeBSDSrcDir}/share/mk \
| distribution DESTDIR=$1 NOMAN=yes)

| echo "==> $i"
| test -d $i &&
| (cd $i ; make -m ${FreeBSDSrcDir}/share/mk \
| install -DNOINFO -DNOMAN DESTDIR=$1 -DNOPROFILE)
| done)
Do you use the gcc embedded optimizations?

| to put this script up, I run into the "oh, but I want it to do X Y and
| Z before posting." problem. Maybe I should just post it.
Just an idea/question:
Can we possibly use crunchgen to generate a big binary for userland tools
only? Then we can drop in new binaries with ease.
However, I think that simply buying a 100mb SANDISK is easier. :)
| : In addition, -CURRENT has become very much larger. I know about
| : the "embedded systems are customized, so cut it down yourself"
| : argument. However, what if it's still large after we cut it down
| : to the bare minimum? Also, what about /dev/random seeding problems?
|
| There are lots of ways to seed /dev/random in an embdeeded system.
Right, I simply hope that Mark Murray can allow us to drop in things
like GPS signal strength and radio background noise. Many embedded
devices have antennas that could be put to good use.
