For each update

bash$ ls man-[0-9]*.rpm

bash$ cp /home/redhat/updates/7.1/en/os/i386/man-1.5i2-0.7x.5.i386.rpm .

Then when finished merging the updates

bash$ rm /home/redhat/linux/7.1/en/os/i386/RedHat/base/hdlist*
bash$ cd /usr/lib/anaconda-runtime/
bash$ ./genhdlist --withnumbers  \

bash$ cd /home/redhdat/linux/
bash$ mv 7.1 7.1-20010921
bash$ exit

The date comes from the e-mail header "Date:" in the mailing to redhat-watch-list@redhat.com. It isn't the advisory's "Issue date" as these are often days before the issue of the advisory and need not be monotonically inceasing.

Obtain the afaapps RPM from http://support.dell.com/. Confusingly the RPM is stored in the file aacraid-util-rh7.1.tar.gz or PRC2UTL2.zip. The documentation for this utility is at

http://docs.us.dell.com/docs/storage/57kgr/cli/en/

Obtain the dellmgr, megaflash, megamon and megaraid-snmp RPMs from http://support.dell.com/. Confusingly the RPMs are stored in the file megaraid-util-rh7.1.tar.gz.

Merge these and other Dell-specific RPMSs using the process above.

Edit

/home/redhat/linux/7.1-.../en/os/i386/RedHat/base/comps

and add the lines

i386: 1 Dell PowerEdge Utilities {
i386:  dellmgr
i386:  megaflash
i386:  megamon
i386:  megaraid-snmp
i386:  afaapps
i386:}

The "comps" file format is not documented, but is reasonably obvious. The mysterious "4" at the top of the file is a version number for the file format. The sections are of the basic form

<wanted> <options> <component> {
  <dependency>
  ...
  <package>
  ...
  <optionalpackage>
  ...
}

Where <wanted> is 1 where the package defaults to being installed, 0 otherwise. <package> is the RPM package.

<options> ::= <nil>
<options> ::= --hide

<dependency> ::= <nil>
<dependency> ::= @ <component>

<optionalpackage> ::= ? <dependency> {
                        <package>
                        ...
                      }

All lines appear to have the form

<condition>: <text>

<condition> ::= <nil>
<condition> ::= !<condition>
<condition> ::= <architecture>:
<condition> ::= (<expr>):
<expr> ::= <term>
<expr> ::= <term> and <term>
<term> ::= arch <architecture>
<term> ::= arch !<architecture>
<term> ::= lang <language>
<term> ::= lang !<language>

The Red Hat Linux kernel is usually a standard Linus kernel with the stable parts of the Alan Cox -ac stream.

The -ac stream tracks the later bug fixes to the Dell megaraid controllers.

Patches for the Dell aacraid controllers can be found at

http://www.domsch.com/linux/

Get the software

bash$ ftp mirror.aarnet.edu.au
ftp> cd pub/linux/kernel/...
ftp> get kernel...tar.gz2
ftp> cd pub/linux/kernel/people/alan/...
ftp> get patch...bz2
ftp> quit

Unpack and apply Alan's patches

bash$ bzip2 -dc linux-2.4.9.tar.bz2 | tar xf -
bash$ cd linux
bash$ bzip2 -dc ../patch...bz2 | patch -p1
patching file ...

Check that the aacraid patches aren't in the kernel yet.

bash$ find . -name 'aacraid*' -print

Get the aacraid software from http://www.domsch.com/linux/ and apply it.

bash$ cd ..
bash$ wget http://www.domsch.com/linux/aacraid/linux-2.4.9-aacraid-20010816.patch
bash$ cd linux
bash$ patch -p1 < ../linux-2.4.9-aacraid-20010816.patch

Manually fix rejected chunks

find . -name '*.rej' -print

Check the currently used compiler

bash$ less Documentation/Changes
The recommended compiler for the kernel is gcc 2.95.3 or .4...  Note
that gcc 2.7.2.3 is no longer a supported kernel compiler...
egcs-1.1.2 has register allocation problems...  The Red Hat gcc 2.96
compiler subtree can also be used to build this tree.  You should
ensure you use gcc-2.96-74 or later. gcc-2.96-54 will not build the
kernel correctly.

bash$ gcc --version
2.96
bash$ rpm -q gcc
gcc-2.96-85

Install the configuration used to build the Red Hat kernel

bash# rpm -ivh kernel-source

Configurations are in /usr/src/linux-2.4.3/configs/. Check that aacraid and megaraid are made into modules

bash$ mkdir configs
bash$ cp /usr/src/linux-2.4.3/configs/* configs
bash$ grep 'CONFIG_SCSI.*RAID' configs/*
CONFIG_SCSI_AACRAID=m
CONFIG_SCSI_MEGARAID=m

Alter /usr/lib/anaconda-runtime/mk-images.i386 to add megaraid and aacraid. Add the RAID modules whereever the SCSI drivers (say aic7xxx) are mentioned.

LOCALMODULES="$COMMONMODULES BusLogic aic7xxx megaraid aacraid
ncr53c8xx sym53c8xx $IDEMODS $SCSIMODS"

Alter /usr/lib/anaconda-runtime/upd-instroot to add megaraid and aacraid.

Configure the kernel based upon the Red Hat Linux configuration.

bash$ cp configs/... .config
bash$ make oldconfig

This displays kernel parameters that were altered since the Red Hat kernel was built. Record these in AARNet.txt and keep a copy of the changed configuration variables handy in newconfig.txt.

bash$ make dep
bash$ make rpm

You'll need to have /usr/src and below owned by the building user (preferrably not root).

Repeat this step for each kernel configuration. You find the simplest way to do this is to repeat

bash$ cat configs/... newconfig.txt > .config
bash$ make dep
bash$ make clean
bash$ make spec
bash$ make rpm
bash$ mv kernel-2.4.9ac15.rpm kernel-2.4.9ac19.smp.i686.rpm

for

kernel-...i386.rpm
kernel-...i586.rpm
kernel-...i686.rpm
kernel-smp-...i386.rpm
kernel-smp-...i586.rpm
kernel-smp-...i686.rpm
kernel-enterprise-...i686.rpm

Note that the kernel-BOOT…i386.rpm configuration is signifacntly different from the other kernels and the new configuration variables should be tailored by hand to be minimal.

Generate kernel-headers-…i386.rpm, kernel-pcmcia-cs-…i386.rpm, kernel-doc-…i386.rpm somehow !!!

Alter the file

/home/redhat/linux/7.1-…/en/os/i386/AARNet.txt

to sumarise the differences between this build and stock Red Hat Linux.
