[parted-devel] [ PATCH ] extended attributes support on ext2 and ext3 filesystem

Hello list.

With this patch I would like to put something on the table :)  We have
had discussions as to the relevance of file system support in parted.
The argument that parted is just to edit partitions has been thrown
around a log and has its merit. I am for stripping parted from all 
its file system code with exception for the bare essentials.  That is,
stuff that detects file systems and stuff that tells us the state of the
file system when we are resizing (Can't think of anymore).

My reasoning for this is that the file system tools do a much better job
at handling file system related stuff like creation, clean removal,
resizing (especially resizing), handling of special cases...  Also, it
seems overkill to repeat file system code.

just my 5 cents.

Regards.


PS:  Christian: watch out for lines ending in space and tab.
