Seen this in the Current (pre-release) ChangeLog for x86 (32-bit):
Actually, dropping back from 5.01, which has a bug that prevents extra
options given at the boot prompt from being passed to the kernel.
We'll look at this again when 5.02 comes out.
Slackware's installer make use of this feature and this reminds me that I could share a little tip.
In addition to passing options to the kernel (and possibly modules) it is possible to set a shell variable in the command line and use its value after booting. You can even quote it. For instance if I write following boot command line:
Linux didier="dumb bunny"
once logged in after booting I get this:
root@slackware:/ echo $didier
I just tried that inside Slackware's installer, I'll check that it works on an installed system.
PS sorry for the missing code tags, there seems to be a bug in the parser used by this forum.
