use install paramter in postinstall script

[Aleksandar Lazic]

Dear List,

we read the paramters of the boot prompt like this.

###
%pre --interpreter /usr/bin/python
.
.
rdLine = (open("/proc/cmdline", "r").read())
offNUS = (rdLine.find('nus') == -1) and (rdLine.find('nlis') == -1)
onRaid = rdLine.find('hwraid') == -1
onInst = rdLine.find('install') != -1
.
.
###

Please can you tell me how I can use this variables in the %post
section, maybe I have missed some documentation in the internet.

Thank you

Aleks
