[PATCH 0/2] Fix for self-hosted-image

[PATCH 0/2] Fix for self-hosted-image

[Paul Eggleton]

Allow additional options when running tune2fs -j on ext3 images and use
that to specify -m 0.5 for self-hosted-image.

Note these patches should be applied on top of Saul's recent
self-hosted-image patch once that is merged.

The following changes since commit 7c794db563cc35f6deaab1dd0fef35015d47e567:

  self-hosted-image: Increase space for build and allow builder user sudo access (2012-04-04 16:16:27 +0100)

[PATCH 1/2] classes/image_types: add IMAGE_TUNE2FS_ext3

[Paul Eggleton]

Add a variable that allows additional options to be passed to tune2fs,
such as -m to control the amount of space reserved for root.

This could potentially be added for other filesystems, but right now we
need it only for ext3 for self-hosted-image.

[PATCH 2/2] self-hosted-image: decrease reserved space to 0.5%

[Paul Eggleton]

The default amount of reserved space for ext2/3 is 5% - this amounts to
about 2GB of a 40GB filesystem that the builder user can't make use of.
We don't need this much reserved so peg it back to 0.5% which should be
more than enough.

I'd prefer something like

IMG_POSTCMD_<fstype>

So it is generic enough to not be confusing for other filesystems.

Please look at my comment about a possible alternative way of doing
it, in a more generic one.

Are you suggesting this would hold the entire post-command to be run? If not, 
what other post command could we be referring to in the case of other 
filesystems? (tune2fs being valid for ext2, ext3 and ext4).

Cheers,
Paul

Yes; it is more generic and for someone using it, it makes no
difference in complexity et all.

Actually it does, but I can see some value in it. v2 on the way.
