innobackupex fails with relative paths

[arcadius]

innobackupex changes the current directory inside it, so if I give it BASEDIR and/or INCREMENTAL-DIR as relative paths:

# /usr/local/bin/innobackupex --use-memory=4G --apply-log --redo-only all-2015-02-28_22h28m-backup --incremental-dir=all-2015-03-03_22h34m-backup

.. , they become invalid & innobackupex outputs smth like:

Maybe, input paths should be expanded with realpath command.

Verified with 2.2.9. While prepare incremental , innobackupex fails with relative path.

There is a different error for the same problem (relative path in incremental-dir) for 2.2.10
