A boot flag is always irrelevant when set on a logical partition. A boot flag is irrelevant on every Debian system's HD0 not also containing bootable DOS, Windows and/or OS/2 if Debian bootloader code (Grub, Lilo, Syslinux, etc.) is present in the MBR of HD0. The primary purpose of a boot flag is to be found by DOS/Windows/legacy-compatible MBR code, which can only make use of it if found on a primary partition that also contains a bootable filesystem or other bootloader code in the partition's PBR. A secondary purpose of a boot flag is for legacy operating systems to determine which primary partition is to be assigned a drive letter. IOW, if a PC only has Debian and uses Grub, Lilo, Syslinux or other bootloader packaged by Debian and installed to MBR to boot, a partition boot flag is always irrelevant. -- "The wise are known for their understanding, and pleasant words are persuasive."
