zogftw makes using multiple geli-encrypted single-vdev ZFS pools for backups more convenient, mainly by automating creation, import and export of such pools and by synchronizing datasets without the user having to manually specify the names of the snapshots that should be sent. geli passphrases can be stored gpg-encrypted which allows importing several pools in a row without having to specify each passphrase manually. zogftw is extendable in shell. It can be sourced from other shell scripts or interactive shells.

Zrep is an enterprise-grade, single-program solution for handling asynchronous, continuous replication of a zfs filesystem, to another filesystem. That filesystem can be on another machine, or on the same machine. It also handles 'failover', as simply as "zrep failover datapool/yourfs". This will conveniently handle all the details of - Making 'yourfs' be a data destination, rather than a source - Making 'yourfs' be read-only - Making the destination fs be "live", and ready to transfer data to yourfs

zsd (ZFS snapshot destroyer) is a zfs(8) wrapper to destroy snapshots on a given dataset using a more convenient interface. The number of snapshots to destroy can be specified directly, or indirectly by specifying the number of snapshots that should be kept. It goes nicely with zogftw's zogftw_snapshot_successfully_sent_hook() to grow a certain number of snapshots on new datasets while keeping the number of snapshots on old datasets constant.

Zxfer is a fork of zfs-replicate. It allows the easy and reliable backup, restore or transfer of ZFS filesystems, either locally or remotely. Some of the features zxfer has: * Written in sh with only one dependency, rsync. Rsync mode is not used in a typical restore, hence in that situation all you need is the zxfer script, your backup and an install CD/DVD. * Reliability is first priority - the only methods of transfer allowed are those that checksum/hash the transferred data. * Transfer to or from a remote host via ssh. * Recursive and incremental transfer of filesystems (via snapshots). * Transfer properties and sources of those properties (e.g. local or inherited). * Override properties in the transfer, e.g. for archival purposes it is useful to override "copies" and "compression". * Create all filesystems on the destination as necessary. * A comprehensive man page with examples. * Can be set to beep on error or when done, useful for long transfers. * Features an rsync mode for when two different snapshotting regimes are on source and destination, and zfs send/receive won't work.

U-Boot loader for A13 Olinuxino. To install this bootloader on an sdcard just do : dd if=/usr/local/share/u-boot/u-boot-boardname/u-boot-sunxi-with-spl.bin of=/path/to/sdcarddevice bs=1k seek=8 conv=notrunc,sync This version is patched so that: * ELF and API features are enabled. * The default environment is trimmed to just what's needed to boot. * The saveenv command writes to the file u-boot.env on the FAT partition. * The DTB file name is chosen based on the board model and passed to ubldr.bin using the fdtfile env variable. ubldr.bin loads the DTB from /boot/dtb/ on the FreeBSD partition. * By default, it loads PIE ubldr.bin from file ubldr.bin on the FAT partition to address 0x42000000, and launches it.

Uptimed is an uptime record daemon keeping track of the highest uptimes a computer system ever had. It uses the system boot time to keep sessions apart from each other. Uptimed comes with a console front-end to parse the records, which can also easily be used to show your records on a web page.
