Category 3: popular/very common and makes the system more robust
----------------------------------------------------------------
Rationale: having these built in makes the system more robust, also
in case of failure
- ahci (default storage for all new systems; means that there the
system always has the / device driver)
This isn't the default for all new systems -- lots of folks boot off
SCSI/RAID.
... and then have the cdrom hang of ahci.
What cdrom? ;)
Category 4: VERY popular
------------------------
Rationale: pretty much always loaded in default installs
- snd_seq_dummy, snd_seq, snd_seq_device,
snd_pcm, snd_timer, snd_page_alloc, snd
Completely useless and unwanted on servers/HPC nodes.
yet tends to get loaded ;)
Not on my systems!
It seems that there's an assumption here that Fedora = desktop.
While there's obviously a lot of that, I've seen it on a fair number
of servers and it is a great fit for HPC nodes.
No that wasn't my assumption actually. My assumption was that those
things are either always loaded, extremely likely loaded by default or
for robustness (say AHCI). I realize it won't hit 100% but... the worst
case downside is a tiny bit of wasted memory. Yawn.
With the upsides I mentioned in my mail.. for me it's worth the
tradeoff for at least almost all of these.
I can definitely see that point of view -- just throwing a few things out
there.
Thanks.
