Re: [suse-autoinstall] applying patches

9 Sep 2002

      Hello,

I have written a script to generate a new common.pkd after an
upgrade of the rpms in the installation directory. I hope someone
find it usefull. On my server the script takes a long time:
   # time gen_common_pkd 
   real    8m32.052s
   user    6m50.890s
   sys     3m5.250s

(Perhaps someone find a solution to make the script faster.)
I include the script in the mail body to avoid an attachment.

# gen_common_pkd - makes common.pkd
