Now that the Installer is of interest again, I wanted to ask if
this idea could make a better sane default for the Installer's
/etc/mke2fs.conf - Meaning when you create and format ext2/3/4
(any others?) partitions.

-m [reserved-blocks-percentage]
"Specify the percentage of the filesystem blocks reserved for the
super-user. This avoids fragmentation, and allows root-owned
daemons, such as syslogd(8), to continue to function correctly after
non-privileged processes are prevented from writing to the filesystem.
The default percentage is 5%."

Now it seems this reserved space is unavailable to users and now that
Hard Drives are massive, this 5% is alot of space.

Would the option -m1 or even -m0 be a better sane default?

or maybe even user defined?

Thanks.
This task depends upon

Reason for closing:  Upstream
Additional comments about closing:  Defaults are set upstream. An end user should be sane enough to modify this file.

I don't think we really need to change the defaults. It complicates things, we'd need to do a check for partition size first too (I use small partitions for my Arch installs.. 4-6gb).

Besides people can set it after the install easily enough.

Yes, please add some more hand holding. We are too affraid to cross the road ourselves: we need wider pavements for pedestrians, streetlights that make the sun ashamed of its output, bigger pedestrian crossings with fluorescent borders, more regulatory signs at least 1 km ahead of the actual road crossing. All pedestrians should be given selfdeploying fluorescent lifejackets by their governments and a brochure "what to do" when they get hit by a car. A police cruiser and ambulance should be 24x7 nearby. Also, ALL drivers wishing to drive over the road crossing must be take a breathalyzer test.

A percentage is a really bad way to determine needed space.
If you have a 1TB drive and take 5% you'll have 50GB.
Why in the hell would you need 50GB of space for super-user
applications?

It should really be defined by MB. That way you'll have the
right size partition whether you have a small drive or a
huge drive.

Just make JFS the default. No fancy options, no worries.

:p
