19 Thank you Rich, I suspected it was an intentional change and from a security
20 perspective it is to be commended. However, it could cause uninformed users
21 like myself some lost time, thinking something may have gone wrong on our
22 system.

28 I think a news item although useful, on its own is not sufficient. If
29 remounting 'rw' and back again to 'ro' is not performed by the legit commands
30 which touch efivars (e.g. efibootmgr, GRUB, et al), the HandBook should also
31 be amended if it hasn't been already, because newbies will have one more
32 excuse to pack it in and go back to *buntu.
