Projectmanager: Important

+ openSUSE-11.4: Unconfirmed
+ Priority
+ Requester: Mandatory

Requested by: Stephan Kulow (coolo)
Partner organization: openSUSE.org

Description:
We need a feature to track the many little pieces needed to make
booting fast.

Business case (Partner benefit):
openSUSE.org: Everyone loves fast boot. Other distributions claim to
maintain the crown.

Didn't mean to save the feature yet, sorry. I meant to add: We need a
feature to track the many little pieces needed to make booting fast.

Working suspend > fast boot.

#4: Stephan Kulow (coolo) (2009-09-07 14:00:07)
we boot faster, many testers noted that. If we boot fast enough to ship
is up to PM

Hello,
I've read over the comments in https://features.opensuse.org/305326.
I'm able to contribute to this feature and not only able but eager of.
I'm not a Linux expert but more of a fan with some coding experience
:), I'm might need some guidance and ramp up time.
Please tell me where to take this discussion to so that I can start
getting involved practically.
I believe we should follow "a tackle the very root of all evil", if
possible. But it is still to be discussed the specific approach to be
followed.
Thanks for your help.
Ulises

Let's starts asap for 11.3 and get it perfected by the time openSUSE
12.0 milestones are available.

Send in your patches now!

bash is a little bloated, and everybody knows it. That is where one
should probably start.

#9: Stephan Kulow (coolo) (2010-01-25 16:33:11) (reply to #7)
"a little bloated"? If you can measure any boot time difference or any
sign of bash causing significant portion of the current boot time we
should start there. Until then I think you should start with finding
out what the problem is instead of claiming things.

Oh on another note, some kernel modules were compiled-in in newer
kernels (such as ext3). IMHO, the idea is good, but I cannot agree with
a number of =y/=m choices that have been done in config/x86_64/default,
and the it seems that the discussion we had on the mailing list did not
really get anywhere, because people insisted that "oh let's include
PIIX=y because that's "common"" (this has reverted as of late, but I'm
just saying).
CONFIG_BLK_DEV_SD=m should be =y (heavily used, by libata and USB)
CONFIG_ATA=m should be =y (used by, well, ATA devices which I guess
many have)
CONFIG_EXT3_FS=y should be =m (thanks, but I am running ext4/xfs and
don't want to waste for ext3).
And so on.

#11: Stephan Kulow (coolo) (2010-01-25 16:34:46)
I close this feature as done. Booting fast is mainly about avoid
regressions and only in a second step speeding up piece by piece. For
11.2 we integrated tons of patches to boot faster, now the biggest task
is ongoing: avoid booting slower.
