Bug#1031738: installation-guide: documentation about limits to kernel boot parameters is outdated

Source: installation-guide
Followup-For: Bug #1031738
Control: tags -1 patch

Please note: the patch previously offered here isn't suitable; it turns out
that the param limits described in it (32 for Linux, 128 for User Mode Linux)
apply only to the number of argument items that are passed to the 'init'
process from the kernel command line -- not to the number of known kernel
parameters ('ro', 'quiet', and so on) that a kernel will accept at boot-time.
