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

Should be added to page, but I'm too lazy

bogus warning about overwriting the entire disk
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
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
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
