Hi,

had some issues while building a new alpine lx zone image based on version 3.7

install script to create tarball:

Fix for alpien 3.7 where /usr/bin/su is not existing when trying to remove $INSTALL_DIR/usr/bin/su
so fist check if it exist

log showed

==> Making /usr/bin/su symlink relative
rm: cannot remove '/tmp/alpine/usr/bin/su': No such file or directory

the the exclude patterns in the exclude.txt used could potentially contain path that holds the entire chroot dir. For example if you use /tmp/xyz to build the tarball.
-> added dynamically created --exclude options based on the exclude.txt but dynamically adding the $INSTALL_DIR

# /install -r 3.7 -a apk-tools-static-2.8.2-r0.apk -d /tmp/alpine -m http://mirrors.gigenet.com/alpinelinux -i alpine-3 -p "Alpine Linux" -D "Alpine 3.7.0 64-bit lx-brand image." -u https://docs.joyent.com/images/container-native-linux
==> Installing Alpine into /tmp/alpine
...
==> Installation complete!
==> alpine-3-20180209.tar.gz
# ls -lth
total 52K
-rw-r----- 1 root    root      45 Feb  9 19:39 alpine-3-20180209.tar.gz

# tar tzvf alpine-3-20180209.tar.gz 
#

create-lx-image script:

as your can use any path as chroot in the install script the --strip-components=2 could potentially be the wrong amount of components to strip. So determinate the amount automatically

hope the contributions are helpful

regards
Joeri
