Hi Francis,

can you please have a look at the code review I attached to your patch, and while on it, also add a patch for the loader(8) man page?

As soon as that's done, I'll commit it. Sorry for the delay!

Cheers,
Alex

Submit #2373: Tunable for suppl. delay before vfs_mountroot()

My Acer Aspire One (mod. D257) HDD takes quite a while to answer its first actual data requests after boot. When vfs_mountroot() comes in, the default 2 seconds delay after sync_devs() isn't enough (starts working ok with 3 seconds here) and this results in the slice table and parts not being probed yet (so i'm thrown at the 'mountroot>' prompt where issuing '?' several times finally displays my slices, etc.)
The attached patch adds a tunable ('vfs.root.wakedelay' - better ideas welcome) to tweak it if ever needed via loader.conf.
Thanks to swildner@ for his friendly guidance!
