# We want to get rid of DHCP in favour of Kea package, because ISC has announced
# the end of maintenance for ISC DHCP as of the end of 2022. No package depends
# on dhcp-server, but dhcp-client is still being used, so we keep it around as
# deprecated package. There is ongoing effort to replace it with other options:
# https://fedoraproject.org/wiki/Changes/dhclient_deprecation
Provides:  deprecated()

# NEVER CHANGE THE EPOCH on this package.  The previous maintainer (prior to
# dcantrell maintaining the package) made incorrect use of the epoch and
# that's why it is at 12 now.  It should have never been used, but it was.
# So we are stuck with it.
