On Linux, su(1)'s "-p" flag makes sure the following environment
variables are preserved: $HOME, $SHELL, $USER, and $LOGNAME. The flag
isn't portable, and since we don't set HOME=$SPOOLDIR anymore, there's
no reason to preserve these variables anyway.
Without "-p", we also don't need to set HOME=$INSTALLUSER_HOME, as su(1)
now does that for us.
Use plain POSIX shell syntax to match ".yml" configuration file names.
This is also slightly more correct, as it matches ".yml" only at the
*end* of the file name.
