LilyPond in chroot jail

Setting up the server to run LilyPond in a chroot jail is a complicated task. The steps are listed below. Examples in the steps are from Ubuntu GNU/Linux, and may require the use of sudo as appropriate.

Example script for 32-bit Ubuntu 8.04

## defaults set here

# the prefix (without the leading slash!)
# the directory where lilypond is installed on the system

adduser $username
dd if=/dev/zero of=$loopfile bs=1k count=200000
mkdir $jaildir
losetup $loopdevice $loopfile
mkfs -t ext3 $loopdevice 200000
mount -t ext3 $loopdevice $jaildir
mkdir $jaildir/lilyhome
chown $username $jaildir/lilyhome
cd $jaildir

mkdir -p bin usr/bin usr/share usr/lib usr/share/fonts $lilyprefix tmp
chmod a+w tmp

cp -r -L $lilydir $lilyprefix
cp -L /bin/sh /bin/rm bin
cp -L /usr/bin/convert /usr/bin/gs usr/bin
cp -L /usr/share/fonts/truetype usr/share/fonts

# Now the library copying magic
for i in "$lilydir/usr/bin/lilypond" "$lilydir/usr/bin/guile" "/bin/sh"  \
  "/bin/rm" "/usr/bin/gs" "/usr/bin/convert"; do ldd $i | sed 's/.*=>  \
    \/\(.*\/\)\([^(]*\).*/mkdir -p \1 \&\& cp -L \/\1\2 \1\2/' | sed  \
      's/\t\/\(.*\/\)\(.*\) (.*)$/mkdir -p \1 \&\& cp -L \/\1\2 \1\2/'  \
        | sed '/.*=>.*/d'; done | sh -s

# The shared files for Ghostscript...
      cp -L -r /usr/share/ghostscript usr/share
# The shared files for ImageMagick
      cp -L -r /usr/lib/ImageMagick* usr/lib

### Now, assuming that you have in /mnt/lilyloop/lilyhome,
### you should be able to run:
### Note that /$lilyprefix/bin/lilypond is a script, which sets the
### LD_LIBRARY_PATH - this is crucial
      /$lilyprefix/bin/lilypond -jlily,lily,/mnt/lilyloop,/lilyhome
