Hi,
I am doing some research into filesystems, and I understand that you
are amongst the leading experts on the topic.
I would be really grateful if you could help me by answering some
quick questions regarding Extended Attributes:
1) Apart from the maximum number / size limitations affecting some
filesystems (ext2, ext3, ext4), as mentioned in attr5 / man5 section
of the Linux manual online, are there any other relevant differences
across the filesystems that may create problems in transfering
Extended Attributes (along with the files) across filesystems?
2) Will the attr (also called xattr) functions work equally well on
all the filesystems that support EA? In other words, are the
EA-management implementations across the Unix filesystems
sufficiently standardized?
3) As far as you know, is there any operating system, apart from
BeOS/Haiku, where the indexing and querying processes of EAs are
managed by the operating system itself? Do you think that this
particular feature of Haiku is a really a significant advantage or
not so much?
I imagine that you are very busy with you work, and I would really
appreciate your help.
Looking forward to your reply, I wish you all the best.
Regards,
Tes Bezier
