Would it be cool if I add something on pxelinux? That way I can refer to it from LTSP.

bogus warning about overwriting the entire disk

Talk status
This discussion is still ongoing.

The following warning about overwriting the entire disk is bogus:

First, install the boot sector provided by Syslinux. Use extra care with this command; if count=1 is not given it will overwrite the entire disk rather than just the first 440 bytes:

root #dd bs=440 conv=notrunc count=1 if=/usr/share/syslinux/mbr.bin of=/dev/sda

dd without bs=440 conv=notrunc count=1 is fine when used on a block device. I will remove this remark if there are no objections --Chithanh (talk) 19:25, 25 February 2016 (UTC)

openrc efivars

Talk status
This discussion is still ongoing.

As per gentoo-dev mailing list,

The documentation should be updated to say that with OpenRC 0.28 that you'll have to remount efivars as RW before you can install the bootloader (e.g., grub-install)

The command I use locally to remount rw (since I have configured efivars to be mounted read-only in fstab) is

mount -o remount,rw /sys/firmware/efi/efivars

/boot symlink

Talk status
This discussion is still ongoing.

The instruction to make the symlink :


root # ln -snf . /boot/boot


Appears to not (not always ?) work as intended. See : https://forums.gentoo.org/viewtopic-p-8252790.html

Thinking of it there really seems to be something off :

If issued from the root folder (as happens to be when reaching bootloader installation, when following the handbook), then it would make the link to /, (which can be on a different partition than /boot), that makes no sense

If issued from inside /boot/, this appears to fail as shown in the link

I suggest to eliminate the relation to the installed system's / completely, so to change this instruction to :


root # cd /boot

root # ln -ns . boot
