## Features
+- bootctl link + sysupdate integration
+ - make sysupdate call out to a special varlink dir on completion
+ - bind bootctl link socket in there, which when invoked goes to new dir in
+ /var/ where downloaded kernels+confext+sysext are dropped in (place in
+ .v/) and then does "bootctl link" on them.
+
- a tool that can prep credentials, put them in the ESP, for provisioning
systems for SBC. Should be doing what sysinstall does with the credentials,
and maybe even *be* sysinstall.
