Package: memtest86+
Version: 4.10-1.1
Severity: wishlist
Tags: patch
When installing the memtest86+ package, four GRUB menu entries get added
nowadays:
memtest86+
memtest86+, serial console 115200
memtest86+, experimental multiboot
memtest86+, serial console 115200, experimental multiboot
In order to reduce that, I've added two variables and some if-statements
to /etc/grub.d/20_memtest86+.
In /etc/default/grub:
GRUB_MEMTEST_ENABLE_SERIAL=[true|false]
GRUB_MEMTEST_ENABLE_MULTIBOOT=[true|false]
In addition, I've added a variable holding the memtest86+ serial params:
GRUB_MEMTEST_SERIAL_PARAMS="ttyS0,115200n8"
In /etc/grub.d/20_memtest86+:
Have a look at the patch file.
