[plug] Your laptop could be bricked with a single Linux command

Basically, if you run on UEFI, you need to be careful when dealing with
/sys/firmware/efi/efivars as root.  You can potentially brick your device by
overwriting or deleting files.

Some people have mounted it as read only by adding an entry to fstab,
however the directory needs to be written to during certain updates - so
this is of little value.

Another reason to never use the command "rm -rf /".


Kind regards,

Nick

Hello Alexander,

Not sure what that means, but sounds like more secure by doing that? 

kind regards
