# Create /var/lock/subsys in the init script (rc.apcupsd)
# These days, /var/lock may be on a tmpfs, so we can't assume the dir is there
patch -p1 < $CWD/patches/create_lockdir_in_init_script.diff

# Use /var/lock/subsys as the LOCKDIR in apcupsd.conf
patch -p1 < $CWD/patches/fix_lockdir_in_config_file.diff

# The "--disable-install-distdir" is important - don't remove it.
# If you enable the distribution-specific install, then apcupsd will attempt
# to patch the /etc/rc.d/rc.6 script on your system.  This may be acceptable
# from a single-user standpoint, but for packagers, it's not worth a crap.
# If I'd wanted the Makefile tampering with things outside DESTDIR, I wouldn't
# have used the DESTDIR flag - why is this so difficult to comprehend?
#
# Don't use legacy defines in the netsnmp headers
