# Recreate some directories/symlinks in the rescue system if present.
# Eventually more stuff from $SHARE_DIR/skel could be moved here.
# The main use is for symlinks, as their presence in the source tree
# (under $SHARE_DIR/skel) brings some problems.
# See https://docs.fedoraproject.org/en-US/packaging-guidelines/Directory_Replacement/

# Other file types can be copied using this mechanism,
# but it is probably better to use the COPY_AS_IS variable for them.
# For a directory the difference is that COPY_AS_IS would copy it recursively,
# while this mechanism recreates the directory as empty.

# Try to care about possible errors
