I have a 250MB install of slackware 9 working off a hard disk. I'm
attempting to transplant it to a CD.

Using isolinux, I am able to boot the default kernel and load the initial
ramdisk. It then successfully starts init.

Init calls a script which starts off by mounting the cdrom. It then makes
links in the ram resident root fs for bin, sbin, usr and so on, pointing
to the same directories on the CDROM.

here's the script that does all this.

PATH=/sbin:/bin

echo "mounting the cd from hdc"
/bin/mount -t iso9660 -o ro,suid,dev,exec,noauto,nouser,sync /dev/hdc
/mnt/cdrom && echo "mounted"

# And we start with the files.


# Link in the dirs on the cdrom
FILES="bin boot dev lib root sbin usr" for AFILE in $FILES ; do
echo "/$AFILE -> /mnt/cdrom/$AFILE"
/bin/ln -sf /mnt/cdrom/$AFILE /$AFILE && echo "done" done

echo "Directories linked"
export PATH=/sbin:/bin

echo "CDROM ROOT is:"

/bin/ls -l /mnt/cdrom/
echo ""
echo "press ENTER to continue"
read Answer


echo "linking in files in /etc"

rm -f /etc
mkdir /etc
ln -s /mnt/cdrom/etc/* /etc



echo "make init read new inittab file"

/bin/kill -HUP 1 && echo "done"

exec /etc/rc.d/rc.S || echo "PROBLEMS!!!"




The problem is, after the links are made, "/bin/ls" fails because it can't
find librt.so.6

I thought this was because of symlinks throwing off the dynamic linker,
but then, I had /lib ( on the initrd.img) linked to /preinit/lib, where I
had the necessary libraries for mount and ln.

Also, /bin was symlinked to /preinit/bin on the initrd.img, where I had the
symlinks from sh to bash.

I wonder what I am missing...

Found it.

in the rc.s file, I should be doing

ln -nfs /mnt/cdrom/$F /$F

This successfully breaks the existing link and replaces it with a new one
point to the cdrom's directories.

It's working
