I reinstalled over 700 packages - plt-scheme beeing the only one failing due to
the btrfs link restriction.

I have hit the same issue - tried to run BackupPC with a pool on btrfs
filesystem. After some time the error of "too many links (31)" appeared to me.
Now I'm forced to migrate to some other filesystem...

btrfs only fails when you have hundreds of hardlinks to the same file
in the *same* directory ... certainly not a standard use case.

use snapshots to your advantage:
 - snap source
 - rsync --inplace source to target (with some other opts that have
been discussed on list)
 - snap target
 - {rinse-and-repeat-in-24-hrs}
