# Fix paths for /etc/forcefsck and /etc/fastboot:
cat $CWD/sysvinit.paths.diff | patch -p1 -E --verbose --backup --suffix=.orig || exit 1

# Seems not needed. Commented out.
## Fix failure to show program version:
#cat $CWD/sysvinit.always.define.version.diff | patch -p1 --verbose || exit 1

# Set default HOME=/root to prevent dotfiles in /:
cat $CWD/sysvinit.default.home.is.root.diff | patch -p1 --verbose || exit 1

# Add /usr/local/sbin and /usr/local/bin to the default PATH:
cat $CWD/sysvinit.PATH_DEFAULT.diff | patch -p1 --verbose || exit 1

# Use /dev/initctl instead of /run/initctl ; this is a named pipe and probably
# should be in /dev anyway, but more importantly, having the upgraded package
# expect it in /run breaks shutdown/reboot without manual intervention:
