Given that systemd-boot is ripped out of systemd, and systemd always |
43 |
mounts efivarfs as read/write, there is really no chance of them |
44 |
altering bootctl to re-mount efivarfs on demand. |

|
46 |
Reporting a bug against systemd-boot would probably be a waste of your |
47 |
time since I will almost certainly close it as WONTFIX. ;-) |
