During the installation of 14.1-BETA1 the password of a regular user that is added to the system doesn't get committed to master.passwd correctly and needs to be reset after reboot. Also the home directory of a user when using 'adduser' doesn't populate the users directory with skel nor does it set the permissions of the users directory correctly. This change is likely to be caused by creating separate ZFS datasets for each user when they are created on the system. This will not be caught by people upgrading from 14.0-RELEASE.
The fix has been merged to releng/14.1 and will be 14.1-BETA2 https://cgit.FreeBSD.org/src/commit/?id=1691bcc8b02c0d32dfde359f8a614a55bc98d6da https://cgit.FreeBSD.org/src/commit/?id=01872b366578d071e9fb981a2fda216379915ce3
