Hi Holger, Thanks for picking up this long-stale bug :)
It looks like sometime in the intervening 10 years this restriction has been fixed, or perhaps just lengthened, but I just booted a live CD with GRUB and a 260 character kernel command line and it was *not* truncated. Rather than quoting a specific 255-character limit, perhaps just mention that particularly long kernel command lines may be silently truncated? cheers Russell On Mon, Jul 03, 2017 at 06:25:20AM +0200, Holger Wansing wrote: > Control: tags -1 + pending > > > russell muetzelfeldt <russm-debian-b...@slofith.org> suggested: > > Package: debian-installer-manual > > > > Section B.2.2 (Using boot parameters to supplement preseeding) notes > > that current kernels can accept a maximum of 32 command line options, > > but says nothing about a maximum number of characters on the kernel > > command line. > > > > There appears to be a 255 character maximum for parameters, after > > which the kernel command line is silently truncated.
