Heiko,

I'm sorry for delay - I forgot to pay the bill and ISP blocked my account from
December, 1... :-\

It's the first good news for me today :-)

:-)  I tried to do that.
To define filename for the file I should know minor version of the kernel patch
or add asterisk as a mask. I mean KERNELVERSION returns 2.6.23 (in my case) but
the patch has name patch-KERNELVERSION.MINOR_VERSION.bz2 (2.6.23.9). If I use
the pattern patch-KERNELVERSION.*.bz2 I get false positive, so I have to make
the pattern narrower...

'man bash' helps me :-) and I've created the next variant:
