As of 1.6.0-r1 it is no longer possible to run "jalv" in the background (with disconnected std FDs). 3a46e861b5b provides an "-i" option to make this possible again. Since it's a trivial, backwardcompatible fix to this regression, I thought it could be backported for the time being.
Thanks, fixed by git commit 257d344317af170a10a0b7e5b49018704bb2a592 (1.6.0-r2).
