The only affect it has is to present boot menu even if otherwise 
disabled, so in principle it is safe to leave. But still ...

address@hidden:~/src/topgit-master$ grep -rw recordfail /etc/init.d
/etc/init.d/grub-common:        grub-editenv /boot/grub/grubenv unset recordfail
address@hidden:~/src/topgit-master$

Well, documentation has to be written by someone. Send patches. No need 
to write treatise, even small additions, fixes and clarifications are 
helpful.
