Further to that ... on recent Fedora I get
$ zdump -v Europe/Dublin | grep 2024
Europe/Dublin Sun Mar 31 00:59:59 2024 UT = Sun Mar 31 00:59:59 2024 GMT isdst=1 gmtoff=0
Europe/Dublin Sun Mar 31 01:00:00 2024 UT = Sun Mar 31 02:00:00 2024 IST isdst=0 gmtoff=3600
Europe/Dublin Sun Oct 27 00:59:59 2024 UT = Sun Oct 27 01:59:59 2024 IST isdst=0 gmtoff=3600
Europe/Dublin Sun Oct 27 01:00:00 2024 UT = Sun Oct 27 01:00:00 2024 GMT isdst=1 gmtoff=0
So Red Hat is indeed moving in the direction of adopting the vanguard
data; they just haven't pulled that trigger yet in RHEL.
