I wondered about that, but the blktrace package doesn't containg
any utility for remapping blocks. The blktrace-0.99.3-12 package
included in OSuse-10.3, I only see utilities "blkparse, blktrace, btrace,
blkrawverify, btt, and verify_blktrace".
Was it left out by accident? ---or---
If the remapping is in a separate package, then shouldn't
the blktrace package "just" do the block tracing, regardless
of file type (i.e. in typical unix fashion, it does its part, and
another util (a block-re-arranger) does its part...?
Having blktrace do it's thing no matter what filesystem
follows might encourage or enable someone to write re-arrangers
for other filesystems...(?) After all, xfs already has
one block-rearranger program (for what little it is needed)
in "xfs_fsr". Does ext3 have something similar now?
Was the ext3 block re-arranging tool supposed to be
in the blktrace package?
