Subject: Selective Compression/Encryption
Date: Tue, 9 Dec 2008 09:59:52 -0500 [thread overview]
Message-ID: <20081209145952.GA30494@tux64-03> (raw)
Currently compression and I assume if encryption is implemented it is
turned on or off during mount. There are however many times when a user may
want to select which files/directories they want to compress or encrypt.
This will also be helpful when implementing btrfs support in grub for
example. We can say the disk can be compressed/encrypted except for /boot so
compression/encryption doesn't have to be implemented in grub.
I was thinking of adding this functionality to the userspace application
btrfstune. The way I was thinking of doing this is when btrfstune +c is
applied to a directory or file the directory(and all its contents) or
file will always be compressed reguardless of how the filesystem is
mounted. The opposite would happen when btrfstune -c is used.
Would this be a reasonable thing to implement? Any suggestions before I
start doing this?
