Crochet: SwapFile creation, Growfs, and Beaglebone FDT fixes

[Tim Kientzle]

I fixed a bunch of Crochet issues this weekend.

= BeagleBone and RadxaRock no longer create swap by default.  If you want to create a swap file on first boot, you should request it via

     option SwapFile 512m deferred

(see config.sh.sample for more details)

= SwapFile is more robust.  SwapFile will only create a swap file on first boot if that would leave at least 2048mb of free space.  In particular, you can now put a growable image with a large swapfile setting onto a small SD card and the first boot logic will just skip the swapfile creation.  (The 2048m free space requirement here can be overridden by setting swapfile_create_free_mb in rc.conf.)

= Growfs now uses the standard rc.d/growfs script that JMG added to FreeBSD-CURRENT (which is a great improvement over Crochet’s original implementation).

= Firstboot scripts work:  Crochet now includes a /firstboot marker file on images which is required for some rc.d scripts to work correctly.  (In particular, this is required for growfs.)

= FDT fixes.  Beaglebone FDT files are correctly generated again.

Cheers,

Tim

P.S.  For anyone interested, here is the BeagleBone Black configuration file that I use myself.  I wish it could install packages, though; then a config file could represent a complete appliance definition.
