Features:
+* homed: allow login via username + realm on getty/login prompt. Then rewrite
+ the user name in the PAM stack
+
+* homed/userdb: add "aliases" field to user record, which can alternatively be
+ used for logging in. Rewrite user name in the PAM stack once acquired.
+
+* confext/sysext: instead of mounting the overlayfs directly on /etc/ + /usr/,
+ insert an intermediary bind mount on itself there. This has the benefit that
+ services where mount propagation from the root fs is off, an still have
+ confext/sysext propagated in.
+
+* marry pcrlock + signed pcr policies for FDE/credentials by letting each
+ unlock "half" of the volume key, so that the combination of both must be
+ XOR'ed to get the actual volume key
+
+* support F_DUDFD_QUERY for comparing fds in same_fd (requires kernel 6.10)
+
* generic interface for varlink for setting log level and stuff that all our daemons can implement
* use pty ioctl to get peer wherever possible (TIOCGPTPEER)
