Other Help Topics :: Low ram machines and *.dsl extentions

If you have a low ram machine. and want to use *.dsl exention. you may run soon out of memory.
i have made a small change to the /etc/init.d/mkwriteable script to use a ext2 partition instead of ramdisk.

Code Sample

#!/bin/sh

# changed to use ext2 hdpartition instead of ramdisk
# /cdrom is the ext2 partion i boot from

WRITEABLE_DIR=/cdrom/writeable

if [ -f /etc/sysconfig/writeable ]; then
exit
fi
INSTALLED=""
[ -e /KNOPPIX/bin/ash ] || INSTALLED="yes"
if [ -z "$INSTALLED" ]; then

rm -rf $WRITEABLE_DIR
mkdir $WRITEABLE_DIR

cp -srd /KNOPPIX/usr/ $WRITEABLE_DIR
ln -sf $WRITEABLE_DIR/usr/X11R6/lib/X11 $WRITEABLE_DIR/usr/lib/
ln -sf $WRITEABLE_DIR/usr /

cp -srd /KNOPPIX/bin/ $WRITEABLE_DIR

cp -srd /KNOPPIX/boot/ $WRITEABLE_DIR
ln -sf $WRITEABLE_DIR/boot /
cp -srd /KNOPPIX/lib/ $WRITEABLE_DIR
ln -sf $WRITEABLE_DIR/lib /

ln -sf $WRITEABLE_DIR/sbin /

cp -dpR /ramdisk/var/ $WRITEABLE_DIR
ln -sf $WRITEABLE_DIR/var /

# mkdir $WRITEABLE_DIR/var
# mkdir $WRITEABLE_DIR/
# mkdir $WRITEABLE_DIR/var/lib

rm -rf $WRITEABLE_DIR/var/cache/apt
cp -srd /KNOPPIX/var/cache/apt/ $WRITEABLE_DIR/var/cache
rm -rf $WRITEABLE_DIR/var/cache/apt/archives/lock
cp /KNOPPIX/var/cache/apt/archives/lock $WRITEABLE_DIR/var/cache/apt/archives
rm -rf $WRITEABLE_DIR/var/lib/apt
cp -srd /KNOPPIX/var/lib/apt/ $WRITEABLE_DIR/var/lib
rm -f /var/lib/dpkg

touch /etc/sysconfig/writeable
fi

i put this script in /opt ( and filetool.lst)
and add

Code Sample

echo "mkwriteable ..."
/opt/mkwriteable

to bootlocal.sh

then i make sure NOT to load any mydsl extention at boot time.

nice!

I'm thinking about making a new ext2 partition.
What about once the files are copied? Can I remove the cp lines and just link the directories next time I boot?

that may be posible. it would speedup the next time you boot.
but then you get a mix between livecd/frugal/poormans and hdinstall, i would not go for that.
