Here is a method to create LSB compliant packages

The Linux Foundation is hosting a set of LSB chroot that can be used in order to test LSB compliance of software as part of their ​Linux Standard Base Sample Implementation Downloads page.

You need to get the packages they propose and install them onto your distribution (which is rpm compliant if LSB compliant !)

$ cd $HOME
$ wget http://ftp.linux-foundation.org/pub/lsb/impl/beta/binary/amd64/lsbsi-chroot-4.0.1-1.x86_64.rpm
$ wget http://ftp.linux-foundation.org/pub/lsb/impl/beta/binary/ia32/lsbsi-chroot-4.0.1-1.i586.rpm

As these packages contain overlapping content, if you want to generate for the i386 and x86_64 arches, I propose to you the following installation means, providing the following project-builder configureation:

$ grep vepath ~/.pbrc
vepath default = /home/rinse
$ mkdir -p /home/rinse/lsb/4.0.1/i386 /home/rinse/lsb/4.0.1/x86_64
$ cd /home/rinse
$ rpm2cpio ~/lsbsi-chroot-4.0.1-1.i586.rpm | cpio -ivdum
$ mv ./opt/lsb/si/chroot/* lsb/4.0.1/i386
$ rm -rf opt
$ rpm2cpio ~/lsbsi-chroot-4.0.1-1.x86_64.rpm | cpio -ivdum
$ mv ./opt/lsb/si/chroot/* lsb/4.0.1/x86_64
$ rm -rf opt

The vepath entry in your default configuration project-builder file tells to pb where to look for Virtual Environments (VEs) on your system. In that directory, you have another file describing relevant information for all VEs. Especially, you need to ensure that pb will build now for your newly created VR:

$ grep velist .pbrc
velist default = centos-4-i386,centos-5-i386,centos-4-x86_64,centos-5-x86_64,debian-5.0-x86_64,lsb-4.0.1-i386,lsb-4.0.1-x86_64

Once this is done, pb is now able to generate packages for those LSB chroots.
