Boot Entry mode menu

[gromdar]

Accidently I found a typo in menu definition that prevents burning Optiboot with 8 second wait time. In my case Attiny85
It appears with error on flashing bootloader since the name of bootloader is not resolved :

-C/home/gromdar/Arduino/hardware/ATTinyCore/avr/avrdude.conf -v -pattiny85 -cusbasp -e -Uefuse:w:0xFE:m -Uhfuse:w:0b11011111:m -Ulfuse:w:0xE2:m -Uflash:w:{bootloader.file}:i

It looks like copy paste error in line with definition and in second line. There is:

menu.bootentry.8s_8sec.bootloader.file =

instead of

menu.bootentry.8s.bootloader.file =

After removing this _8sec everything works fine.

Cheers
