Kyle Gospodnetich f9f3913c8b Add configurable bindir for distros without sbin
Adds a `BINDIR` Make variable, defaulting to `sbin`, allowing packagers
to override the install location of `beesd` for systems that do not use
`/sbin`.  This affects the install path and systemd unit template.

BEES

Best-Effort Extent-Same, a btrfs deduplication agent.

About bees

bees is a block-oriented userspace deduplication agent designed to scale up to large btrfs filesystems. It is an offline dedupe combined with an incremental data scan capability to minimize time data spends on disk from write to dedupe.

Strengths

  • Space-efficient hash table - can use as little as 1 GB hash table per 10 TB unique data (0.1GB/TB)
  • Daemon mode - incrementally dedupes new data as it appears
  • Largest extents first - recover more free space during fixed maintenance windows
  • Works with btrfs compression - dedupe any combination of compressed and uncompressed files
  • Whole-filesystem dedupe - scans data only once, even with snapshots and reflinks
  • Persistent hash table for rapid restart after shutdown
  • Constant hash table size - no increased RAM usage if data set becomes larger
  • Works on live data - no scheduled downtime required
  • Automatic self-throttling - reduces system load
  • btrfs support - recovers more free space from btrfs than naive dedupers
