So the summary of all this is, as I understand it: for ext3fs 1.0, treat
it with chattr +S and the like as if it was ext2fs, it may or may not be
faster with "mount -o data=journalled" and is well worthwhile for an MTA
to try, a weaker sync option may be introduced after ext3fs 1.0.
Sounds good.
I'm dropping the ext3-users mailing list for now since this is getting
more general.
However, since the ReiserFS team also showed interest in a similar
functionality, and they don't yet support chattr, would it be useful to
specify a "D" option for chattr already?
I have a suggestion: if D is set, but S isn't, no effect. If S is set,
but D is unset, treat S as in the past. If S is set, and D is set,
directory updates are synchronous like with S, but data updates are
asynchronous in spite of S.
This way, booting a kernel without chattr "D" flag support or mounting
the file system as ext2 would have it default to the safer
everything-synchronously mode.
