eric and mkdir /etc/localtime /etc/localtime is not a directory but a symlink, so create a symlink not a directory. Also, in your boot@ system configuration file, instead of using TZ=GMT use TZ=Europe/London
banned_9-26-2021 On your boot tree you have a module, the default setup by the installer is boot@ system but you may have named it something else, nobody other than you can know this. % sudo 66-intree -zg will show you the module name at the bottom. % sudo -E 66-env boot@ system lets you edit the configuration file from that module % sudo 66-enable -t boot -F boot@ system passes the changes to the module on tree boot It is all in the "wiki" :)
