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?
brld - Starts brld the braille server
sbl - SUSE blinux
brld and sbl are both services to control →braille-devices.
cifs - Import remote SMB/ CIFS (MS Windows) file systems (If I do not have dual boot, do I need this?)
SMB is a service to share data between two machines, it is mostly used when at least one Windows-system is involved.
random - Script to snapshot random state and reload it at boot time.
I’m not sure either…
sshd - Do I need this if I won’t be SSH-ing into this computer, ever?
No.
random is not a service (well, I call a service a deamon that is (normaly) running during the lifetime of the sytem and serves to clients either overthe network or localy).
I assume you mean the start/stop script /etc/init.d/random. It just runs (with the start parameter of course) on the start of the system and (with the stop parameter) on shutdown. It saves data to be used at reboot thus that the random number generator is more random (not starting with the same number allways). It reads this from the kernel and writes it there using /dev/random.
And for SMB, this is often called Samba. Just for when you want to read more about on the internet (Wikipedia).
