 |
|
Ok, here is the output from
modules | boot
nas |
net.eth0 | default
net.lo | boot
netmount |
nscd |
ntp-client |
ntpd | default
numlock |
portmap |
raid5 | default
rmnologin | boot
rsyncd |
samba |
sendmail |
serial | boot
slapd |
slurpd |
spamd |
sshd | default
urandom |
usermin |
vixie-cron | default
webmin |
winbind |
xdm |
xfs | default
What are all these for and what can I disable to make it boot faster?
It seems to stall at bringing up lo. Do I need that? |

The only ones that get started when you boot are the ones with a runlevel (like "boot" or "default") after them. If there's something there that you don't recognize, and it's in a runlevel, you can remove it with the command:
| Code: | | # rc-update del <service> |
Just make sure you know what you're removing before you do it.

Well to make it boot faster you could ditch....
xfs: Not totally sure what it does (other than "something to do with fonts") - it's not necessary
vixie-cron: If you don't have any cron jobs, disable it
serial: For the serial port
sshd: Not necessary for boot
Obviously if you're using any of the above then you'll want to leave them in. Otherwise they're not needed.
raid5: One assumes you're running on one if you've got this there? Probably best to leave alone.
I don't know what ntpd and rmnologin do - mine doesn't have ntpd so it may not be needed either. |

/etc/init.d/ntpd starts the ntpd service, which sets your clock using the network time protocol. Unless you don't want to have an accurate time on your clock, leave this one alone. Incidentally, ntpd allows your computer to act as a local timeserver, so other computers on the network can set their time off of yours (and thus keep from overloading the stratum servers). I don't notice it taking up any time during boot.

Well isnt xfs necessary for Antialiased fonts? Also I use ssh all the time. Its just like the following that i am not sure about:
net.lo and rmnologin
The reason I ask is that booting stalls for a good 20 seconds while bringing up lo. Just wondering if its necessary.
also, what is slapd and slurpd? |

xfs is use for font caching. It will speed up performace when u use antialiases fonts in x-windows.
slapd is use for openldap services
