Comment 6 for bug 1848144

Looking at the casper code, it seems to me that it actually was never written to properly work. The ubiquity-hooks/30accessibility hook basically only really acts on accessibility options passed via the cmdline. There is some strange code that seems to be for like a second pass for $UBIQUITY_A11Y_PROFILE, but it seems to be only set in /usr/bin/casper-a11y-enable - which is only ran if there are kernel cmdline options set.
