An odd title for a post, but I found the -F flag for the mount command, which forks off the command for each mount point, rather than waiting for the system to complete each command sequentially. It shaved about a half a second off my boot time, which really isn’t enough to make a huge difference.
And it comes with a warning: If you need to have certain mount points assembled in order, you could be causing problems for yourself by using it.
In the rc.sysinit script, line 235 has the mount command; add -F and see if it helps.
