From 31dec3c6d3862dedeab96b1601bc0f2d7190dd85 Mon Sep 17 00:00:00 2001 From: Phil Blundell Date: Sat, 29 Sep 2012 13:20:05 +0100 Subject: opkg: Don't call sync() when installing into an offline root Even when installing onto a live target system, calling sync() during package installation is of somewhat questionable benefit. But calling it on the build host during rootfs construction is certainly useless and can cause I/O to stall for several seconds on even a moderately sized host which is clearly not desirable. (From a patch originally by Mike Crowe.)
