Bug#397592: document max. length of boot parameters



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. I have no idea if this is a limitation of the kernel, or of grub, but it should probably be noted along with the 32 parameter limit.
