Re: This is like BIOS flashing by Unix commands
Yes but not a good design, and no single design element at fault.
A virtual file linking to firmware settings
A dangerous file system delete that I can think of no use for other than fun
Firmware itself also not coded defensively with a set of default settings in the event of them being missing/bad.
Fixing any one is a workaround.
BIOS should reset to factory default if it cant get operable values.
recursive delete of root could be disabled
Admittedly I am a bit light on knowledge of the boot process at this level but I am surprised firmware settings are needed as read/write for normal operations, perhaps this and the associated tools should be looked at so that the default is read-only. (anyone enlighten me on what the writes may be needed for?)
either way this is not specifically a Linux or SystemD problem its a legacy architecture as its always harder to change these integration points with the hardware as neither side can do it alone.
