 > Probably the first boot is slower because of filesystem resizing.

 This is speculation.  We have no proof in this ticket ''yet'' that the
 filesystem resize is responsible for the slowness.  The test results in
 #10040 and elsewhere suggest a time of the order of seconds for the
 resize, not four minutes.  A kernel log of a first boot would verify this,
 since the resize emits progress timestamps there.  Let's look at a log.

 > Why this resize is performed at first boot?

 See #10040 for discussion.  A resize is necessary so that only a single
 image needs to be provided, instead of .zd2, .zd4 and .zd8 according to
 the size of the internal storage of the laptop.  If the resize is not done
 on first boot, then the amount of free space on first boot will be
 incorrect.  First boot seems to be the right time.  Alternative
 suggestions welcome, maybe we missed some opportunity.

 Also, next time you are reporting a boot problem, could you please attach
 a serial cable and see if you can capture console output?  The pictures
 took a long time for me to download.  Let us know if you need serial
 adapter and cable.

 Regarding your trac usage questions; for builds leading up to a release,
 such as os13, the version can be set to "Development build as of this
 date".  Component can be left unchanged if you don't yet know what
 component is likely to be the cause.

 Your first ticket description was very well written, thanks.  Way above
 the quality we normally see.
