---Problem Description---
modprobe does not honor blacklist options in kernel cmdline unless -b is used (at least on the installer)
The modprobe.blacklist option is required as a work-around until a solution to a device-driver bug is found (IBM LTC bug 138273).
I've gone through the code of the kmod src pkg, but didn't spot anything obvious.
Passing along to the Ubuntu team.

---Steps to Reproduce---
Boot the installer w/ this boot/kernel cmdline option (the alias w/ dashes is not required, but is here just in case):
modprobe.blacklist=scsi_dh_alua,scsi-dh-alua
On the dialog for username/password, select Go Back, then Exit to shell:

Boot the installer w/ this boot/kernel cmdline option (the alias w/ dashes is not required, but is here just in case):
modprobe.
On the dialog for username/password, select Go Back, then Exit to shell:
The blacklist is detected/present in the config:
~ # modprobe -c | grep alua
blacklist scsi_dh_alua
blacklist scsi-dh-alua
But the module is insmod-ed anyway:
~ # modprobe -v -n scsi-dh-alua 4.4.0-21- generic/ kernel/ drivers/ scsi/device_ handler/ scsi_dh_ alua.ko
insmod /lib/modules/
Unless -b is used:
~ # modprobe -v -n -b scsi-dh-alua
