NGPT with 2.4.20

Good Afternoon,


today i searched the Mailinglist Archive for Information
about NGPT with linux 2.4.20 because i couldnt find
the appropriate path.
i found some mails regarding this issue and found some
advice to use 2.4.19 patch, too; but i didnt found any
mails reporting success with this solution.

is it safe to use this patch or will i have to make changes ?
i dont think i am skilled enough to do changes to the kernel
code by myself...

another question: when i install ngpt it will overwrite my old
threating library, right (using debian woody at the moment)  ?

what will happen when i reboot the system with unpatched
kernel (lets say something went wrong with the new kernel
and i have to boot an old one) ? will that totally fail or will
i be able to at least restore the files ngpt replaced ?


Thank you very much,
Philipp
