state of the stream. Change argument of the seek function to funopen() from
fpos_t to off_t. Make f{g,s}etpos() use the new fpos_t struct, while providing
backwards compatible entry points. Approved by releng@
and then modified, it is much easier to let this late, user-oriented
customisation be done automatically. These mods let mkimage change
information based on files in a "custom" directory, which can be set
in mkimage using -c customdir.
After all other configuration, the files under custom/ will be copied
into the main image. The files under custom/ are taken into account
when performing autosizing.
Also, generalise the sets directory to point to the current machine
architecture, although this can be overwritten from the command line
by anyone making cross-images.

embedded platform in particular.
+ mkimage will make an autosized image in a file (using vnd) from sets
the resulting image can be mounted read-only, with tmpfs used for volatile
files on top of read-only bases
+ mkpkgs will make an autosized image in a file (using vnd) from binary
packages
+ usermode is an easy way to invoke usermode, making sure that bridging
is set up properly, and that the host syscallemu module is loaded. This
script then runs usermode with two file images (as produced by mkimage
and mkpkgs)

still needed. OK christos, riz.
This is the user/application API and does not include the kernel
interface. Definitions shared with the kernel are found in
<sys/quota.h>.
Since I've been working on a local branch I have taken the liberty of
moving the latest-so-far version of <quota.h> to the front of the
patch queue. This loses (a small amount of) history but has the
advantage of avoiding unnecessary version bumps of libquota.so.
into the kernel if the "IPSEC" kernel option is given.
The old implementation is still available as KAME_IPSEC.
Do some minimal manpage adjustment -- kame_ipsec(4) is a copy
of the old ipsec(4) and the latter is now a copy of fast_ipsec(4).
