General Preparation

sysstat: patching and rebuilding

  • Install the source rpm package rpm -ivh ftp://ftp.redhat.com/redhat/linux/enterprise/5Server/en/os/SRPMS/sysstat-7.0.2-3.el5.src.rpm

  • Find the file that needs to be patched find sysstat-7.0.2 | xargs fgrep -iH sadc -F

  • Backup existing file(s) that are going to be modified, then make appropriate changes cp sysstat-7.0.2/sa1.in sysstat-7.0.2/sa1.in.bak vi sysstat-7.0.2/sa1.in

  • Create a patch file with a header that specifies the executed diff command diff -up sysstat-7.0.2/sa1.in.bak sysstat-7.0.2/sa1.in

  • Examine the first line in the existing patches to see the first line examples head -n1 *.patch | fgrep diff

  • Examine final patch file

diff -up sysstat-7.0.2/sa1.in.bak sysstat-7.0.2/sa1.in

  • Copy and rename patch cp /tmp/diskmod.patch /usr/src/redhat/SOURCES/sysstat-7.0.2-diskmod.patch

  • Examine existing patch directives in spec file for a point of reference

makeme: deploying files

  • Create the files that are going to go in the source tarball**
mkdir -p /tmp/makeme-1.0/dir1
mkdir -p /tmp/makeme-1.0/dir2
touch /tmp/makeme-1.0/dir1/1
touch /tmp/makeme-1.0/dir1/2
touch /tmp/makeme-1.0/dir1/3
touch /tmp/makeme-1.0/dir2/4
touch /tmp/makeme-1.0/dir2/5
  • Build the source tarball**
cd /tmp
tar -czvf makeme-1.0.tar.gz makeme-1.0
cp makeme-1.0.tar.gz /usr/src/redhat/SOURCES/
  • Create /usr/src/redhat/SPECS/makeme.spec**
