Another aside related to file systems and Mandriva:

1) 1K fragments on ext* file systems

	In an attempt to maximize the no. of blocks available
	on user disk storage, Mandriva has traditionally used
	a non-default and smallest possible fragment size.

	Which is fine: until ext3 breaks and RPM (and Berkeley DB)
	is blamed for what is (if true) a kernel ext3 bug.

	Should the fragment size be increased to "default" in 2012?

	Note that Felix Miata has been reporting the issue for years and recently
	(at bugzilla.redhat.com). Noone has ever pinned down the exact
	problem anywhere that I am aware of. Until the actual mechanism
	for the failure is reported in full detail, the bug will continue to be
	reported against RPM (and Berkeley DB) forever imho. Oh well …

2) flash file systems

	There's recent threads here on cooker@ about installs on flash
	drives that are at least plausibly connected to the choice of smallest
	possible block size (yes there are many other causes of slow flash).

	There are also many tunings related to SSD etc, and several different
	choices for what file system toinstall on flash, too numerous to mention.

	What choices for 2012 default? (is the question I put forward while
	enumerating possible 2012 "features")
