usrqouta is very usefull for couting (and limitng) ammount of data put by system users. Its otherwise impossible to quicly calculate disc usage by system users. Btrfs sould support this in future. Usrquota is supported by ext2/ext3/reiserfs and I quess it updates its internal database everytime file is created, deleted, resized or changed ownership... -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
