Oddly, I could not find any info on some of these and limited on others:

brld - Starts brld the braille server
cifs - Import remote SMB/ CIFS (MS Windows) file systems (If I do not have dual boot, do I need this?)
sbl - SUSE blinux
vmtoolssd - (I have VirtualBox, so do I need this?)
random - Script to snapshot random state and reload it at boot time.
sshd - Do I need this if I won't be SSH-ing into this computer, ever?
