## ## Start Default Options ##
## default kernel options
## default kernel options for automagic boot options
## If you want special options for specific kernels use kopt_x_y_z
## where x.y.z is kernel version. Minor versions can be omitted.
## e.g. kopt=root=/dev/hda1 ro
## kopt_2_6_8=root=/dev/hdc1 ro
## kopt_2_6_8_2_686=root=/dev/hdc2 ro
# kopt=root=UUID=2fd70bf7-9a2d-43a9-b98a-e72409caf5aa ro## default grub root device
## e.g. groot=(hd0,0)
# groot=(hd0,0)## should update-grub create alternative automagic boot options
## e.g. alternative=true
## alternative=false
# alternative=true## should update-grub lock alternative automagic boot options
## e.g. lockalternative=true
## lockalternative=false
# lockalternative=false## additional options to use with the default boot option, but not with the
## alternatives
## e.g. defoptions=vga=791 resume=/dev/hda5
# defoptions=## should update-grub lock old automagic boot options
## e.g. lockold=false
## lockold=true
# lockold=false## Xen hypervisor options to use with the default Xen boot option
# xenhopt=## Xen Linux kernel options to use with the default Xen boot option
# xenkopt=console=tty0## altoption boot targets option
## multiple altoptions lines are allowed
## e.g. altoptions=(extra menu suffix) extra boot options
## altoptions=(single-user) single
# altoptions=(single-user mode) single## controls how many kernels should be put into the menu.lst
## only counts the first occurence of a kernel, not the
## alternative kernel options
## e.g. howmany=all
## howmany=7
# howmany=all## should update-grub create memtest86 boot option
## e.g. memtest86=true
## memtest86=false
# memtest86=true## should update-grub adjust the value of the default booted system
## can be true or false
# updatedefaultentry=false## should update-grub add savedefault to the default options
## can be true or false

nm: /boot/vmlinuz-2.6.26-2-amd64: File format not recognizedВопросы:
1) почему не совпадает версия в uname и в названии файла?
2) почему не задекларированы commit_creds и prepare_kernel_cred?
3) может у кого-то есть эта сборка (Mar 13 00:42:43) под рукой?

Как переводится название эксплойта я знаю, но копирайты - святое, особенно в этом конкретном случае.
