# Specific images modifications
# The base image installs kepubify with "curl -o /usr/bin/kepubify", which both leaves it mode
# 0644 and gives it a name calibre-web does not accept : binary_helper.py only takes
# "kepubify-linux-64bit" or "kepubify-linux-32bit", and only when os.access(X_OK) passes. Both
# defects have to be fixed, which is why enabling Kobo sync failed with "Kepubify binary not
# found" even when the path was set by hand. Publish it under an accepted name in /opt/kepubify,
# the directory calibre-web's own autodetect_kepubify_binary() already probes, so calibre-web
# fills the setting in itself. The second link keeps /usr/bin working as well : that is the value
# already stored by anyone who applied the "ln -sf /usr/bin/kepubify /usr/bin/kepubify-linux-64bit"
# workaround, and their setting is not empty, so it is left alone below and has to keep resolving.
# Unguarded on purpose: if a future base image stops shipping the binary, the build must fail here
# rather than ship a silently broken add-on.
