Yes, unfortunately /tmp/partitionfile is not preserved after the system boots.
You can try the following:
1. Set debug on: chdef -t site clustersite xcatdebugmode=1
2. Start installation
3. When node "status" attribute changes to "installing", on Management node run
runcmdinstaller <node> "cat /tmp/partitionfile". There is also a "
/tmp/pre-install.log"
which might have something interesting.

I've checked another node (I'm trying many things), and the result are
different.
So, first node:
grep nouveau /install/autoinst/node-g003-clu
if [ -n "nouveau.blacklist=yes " ];then
sed -i -e /bootloader/s#\'#\"#g -e '/bootloader/s/--
append=\([^"]\S*[^"]\)/--append="\1"/g' -e '/bootloader/s/--
append="\(.*\)"/--append="\1 nouveau.blacklist=yes "/g'
/tmp/partitionfile
sed -i -e '/bootloader/{/append=/!s/$/& -- append="nouveau.blacklist=yes "
/}' /tmp/partitionfile
grep -q bootloader /tmp/partitionfile >/dev/null 2>&1 || echo -e
"bootloader --append=\"nouveau.blacklist=yes \"" >>/tmp/partitionfile
The node definition:
lsdef node-g003-clu -i addkcmdline
Object name: node-g003-clu
addkcmdline=R::nouveau.blacklist=yes nouveau.blacklist=yes
Second node:
grep nouveau /install/autoinst/spiro-g302-clu
if [ -n "earlyprintk=ttyS0,115200 rd.blacklist=nouveau
nouveau.modeset=0 " ];then
sed -i -e /bootloader/s#\'#\"#g -e '/bootloader/s/--
append=\([^"]\S*[^"]\)/--append="\1"/g' -e '/bootloader/s/--
append="\(.*\)"/--append="\1 earlyprintk=ttyS0,115200 rd.blacklist=nouveau
nouveau.modeset=0 "/g' /tmp/partitionfile
sed -i -e '/bootloader/{/append=/!s/$/& --
append="earlyprintk=ttyS0,115200 rd.blacklist=nouveau nouveau.modeset=0 " /}'
/tmp/partitionfile
grep -q bootloader /tmp/partitionfile >/dev/null 2>&1 || echo -e
"bootloader --append=\"earlyprintk=ttyS0,115200 rd.blacklist=nouveau
nouveau.modeset=0 \"" >>/tmp/partitionfile The node definition:
lsdef node-g302-clu -i addkcmdline
Object name: node-g302-clu
addkcmdline=R::earlyprintk=ttyS0,115200 R::rd.blacklist=nouveau
R::nouveau.modeset=0
So it seems that the parameters are added into the autoinst file, but not
applied on the node during installation ...
Some problems with /tmp/partitionfile maybe ?
