From 571df6ddba1caa6805f7c96cd592eea399c2aee2 Mon Sep 17 00:00:00 2001 From: Richard Tollerton Date: Fri, 22 Aug 2014 16:30:48 -0500 Subject: udev-cache: Compress the cache $DEVCACHE is observed to be 100k uncompressed; compressing it reduces its size to ~5k. But compress it outside of `tar` so that archival operation takes as little time as possible, to minimize the risk of devices being created/removed during execution.
