I will answer myself a little bit... now, it is almost a certainty
that
HFS+ is like EXT3. Perhaps, it is like any other journal system (heh, I
donŽt really know what journal system is :),
A journaling file system is a fault-resilient file system in which data
integrity is ensured because updates to directories and bitmaps are
constantly written to a serial log on disk before the original disk log
is updated. In the event of a system failure, a full journaling
filesystem ensures that the data on the disk has been restored to its
pre-crash configuration. It also recovers unsaved data and stores it in
the location where it would have gone if the computer had not crashed,
making it an important feature for mission-critical applications.
jHFS+ being that, I wonder:
If I write from Linux to jHFS+ , what will it happen:
a) I break the partition and Mac OS X freaks out, crashes, and I
have to reinstall Panther again.
Maybe...
b) Since (apparently) the hournal can be activated and
deactivated from the GUI, nothing happens: whatever I added
under Linux can only be seen if I deactivate the journal,
since OS X has not updated it.
I don´t know anything about this
c) The journal is automagically updated in the next boot and
therefore, I donŽt have to deactivate it to work with the new
files from linux :)
This too
Anyone wanna comment? Anyone wanna bet??? :-D
Yes, like i said before, try to not use HFS-Plus write support :-)
