a struct called kernelops, which contains standard system calls
for the normal case and rump system calls for the rump case.
Make it possible to run the lfs cleaner in a library fashion (taking
the quick route with the implementation).
cleaner, but with more legible code.
Includes code for reading and writing to the raw disk device (so that an
unmounted fs could be cleaned), for the use of a single daemon to clean
multiple filesystems to save on resources, and for recording the old
contents of cleaned segments to offline storage for regression testing of
the LFS system as a whole; though these new features are not properly
tested at this point.
be digging itself deeper into a hole, it forks off a subprocess
that locates files with too many discontinuities and rewrites them, if
there is enough room.
Optionally the user can manually coaleasce files by running with "-c".
The recent change to lfs_markv is required for the coalescer to do anything.
All of "digging itself deeper", "too many discontinuities", and "enough room"
need to be better defined.
Let lfs_cleanerd record its pid in /var/run like other daemons. Make
mount_lfs not start another cleaner when updating the mount, unless it is
being upgraded from read-only to read-write; when downgrading to read-only,
kill the cleaner using the recorded pids.
