Edited README, added initial client tools 2012-08-05 19:19:59 -04:00			`#!/bin/bash`

Got dual-mount of the noop/real filesystems working, made all apps aware of it, broke out the initialization logic into disco-fs-init so you can mount/unmount as much as you want, but the time consuming init process won't be repeated unless you ask 2012-08-07 10:33:29 -04:00			`. /etc/disco/client.cfg`

Added real life example to the README, minor fixups to disco and disco-fs-diff 2012-08-17 22:21:29 -04:00			`CREATED=0`

Modified disco-fs-diff to reduce the diff time more than 50% on average 2012-08-19 15:03:40 -04:00			`rsync --checksum --times --perms --owner --group -ani ./scratchfs/ ./rootfs/ --out-format "info: File: %i : %f : mode='%B', size='%l', mtime='%M'" \|\`

Moved disco colorization into a function, can be used standalone with "client/bin/disco colorize" on stdin. Fixed disco-fs-diff to only use rsync, sed, grep, etc to produce the filesystem changelog, python script is gone Minor fixups to other scripts 2012-08-17 19:24:25 -04:00			`while read LINE`

Made the diff stat from inside the testfs, so new users/groups would stat correctly. Changed disco-ball fetch to fetch into the testfs, not into / (yikes!). New disco-ball command spin does what the main disco loop used to do for each module. Added the "users" disco ball to the standard library. 2012-08-23 00:16:22 -04:00			`STAT_NEW=$(chroot ${DISCOROOT}/chroot stat --format "owner='%G:%U', selinux='%C', md5='${MD5_NEW}'" /${FNAME} 2>/dev/null)`

Added the 'packages' disco ball that installs and removes packages for you from parameters. Minor fixups to disco-fs-diff. Fixed a bug in disco-ball where files would not get deleted, and .unionfs was rsynced back into /. 2012-08-23 19:39:07 -04:00			`diff -N ${FNAME} ${DISCOROOT}/scratchfs${FNAME} 2>/dev/null \| grep -v "^Binary file" > /tmp/$$.diff`
