Hello, I am using Debian GNU/Linux as my primary system. As a loader I am using GRUB. Actually I have upgraded to GRUB2. I don't know, if it was feature of original (legacy) GRUB or it was functionality provided by debian scripts (update-grub), for generating menu.lst. There was feature - howmany. This option specifies number of kernels, that user wants to have in boot menu. Script, that modifies menu.lst, use this variable. I like this feature, because I have usually more kernels, but I want to see only last two versions in GRUB menu. I have created patch, that add support for this to /etc/grub.d/10_linux. I have created this patch against version shipped with Debian (1.97~beta3-1) - I don't know if there are some Debian specific modifications. Also there should be variable GRUB_HOW_MANY propagated from /etc/default/grub (my patch don't do this). Kernel and it's rescue variant is counted as one kernel.
I have already reported this bug to Debian BTS: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=548600 Regards -- Jezz mail: j...@hkfree.org jabber: j...@njs.netlab.cz
