2318	ext3 reliability requirements are not met	alexander@…	bdubbs@…	"Pavel Machek published a patch that documents conditions under which the ext3 filesystem is reliable against power failures. These conditions aren't met by LFS systems.

Namely, the failed requirement is: ""either write caching is disabled, or hw can do barriers and they are enabled"". To disable write caching, one should do ""hdparm -W0"" on the device before remounting the filesystem read-write. To enable barriers (if the hardware supports them), use ""barrier=1"" mount option."	task	closed	normal	6.5	Book	SVN	normal	fixed
