Don't carry around Augeas lenses. It is fragile, since if the lens is added to upstream Augeas but the version number has not changed, then Augeas won't parse the target file at all. This specifically causes password adjustments to fail in RHEL 7.1. In future, if we need an Augeas lens, it must be added to Augeas, either upstream or as a downstream patch carried around by distros. --- README | 2 +- appliance/Makefile.am | 6 +--- appliance/guestfs_lvm_conf.aug | 74 ------------------------------------------ appliance/guestfs_shadow.aug | 72 ---------------------------------------- appliance/hostfiles.in | 1 - configure.ac | 3 ++ daemon/augeas.c | 21 +----------- daemon/daemon.h | 11 ------- daemon/lvm-filter.c | 14 +------- 9 files changed, 7 insertions(+), 197 deletions(-) delete mode 100644 appliance/guestfs_lvm_conf.aug delete mode 100644 appliance/guestfs_shadow.aug diff --git a/README b/README index 30e241a..2e7930b 100644 --- a/README +++ b/README @@ -104,7 +104,7 @@ The full requirements are described below. +--------------+-------------+---+-----------------------------------------+ | libxml2 | | R | Popular XML library. | +--------------+-------------+---+-----------------------------------------+ -| augeas | 1.0.0 | R | | +| augeas | 1.2.0 | R | | +--------------+-------------+---+-----------------------------------------+ | xz | | R | Used to compress disk images. | | | | | Used by virt-builder for compression. | diff --git a/appliance/Makefile.am b/appliance/Makefile.am index 7b30bbe..ebc526e 100644 --- a/appliance/Makefile.am +++ b/appliance/Makefile.am @@ -21,8 +21,6 @@ EXTRA_DIST = \ 99-guestfs-serial.rules \ excludefiles.in \ guestfsd.suppressions \ - guestfs_lvm_conf.aug \ - guestfs_shadow.aug \ hostfiles.in \ init \ libguestfs-make-fixed-appliance.in \ @@ -76,14 +74,12 @@ packagelist: packagelist.in Makefile cmp -s $@ $@-t || mv $@-t $@ rm -f $@-t -supermin.d/daemon.tar.gz: ../daemon/guestfsd guestfsd.suppressions guestfs_lvm_conf.aug guestfs_shadow.aug +supermin.d/daemon.tar.gz: ../daemon/guestfsd guestfsd.suppressions rm -f $@ $@-t rm -rf tmp-d mkdir -p tmp-d$(DAEMON_SUPERMIN_DIR) tmp-d/etc tmp-d/usr/share/guestfs ln ../daemon/guestfsd tmp-d$(DAEMON_SUPERMIN_DIR)/guestfsd ln $(srcdir)/guestfsd.suppressions tmp-d/etc/guestfsd.suppressions - ln $(srcdir)/guestfs_lvm_conf.aug tmp-d/usr/share/guestfs/guestfs_lvm_conf.aug - ln $(srcdir)/guestfs_shadow.aug tmp-d/usr/share/guestfs/guestfs_shadow.aug ( cd tmp-d && tar zcf - * ) > $@-t rm -r tmp-d mv $@-t $@ diff --git a/appliance/guestfs_lvm_conf.aug b/appliance/guestfs_lvm_conf.aug deleted file mode 100644 index ffa5b01..0000000 --- a/appliance/guestfs_lvm_conf.aug +++ /dev/null @@ -1,74 +0,0 @@ -(* -Module: LVM - Parses LVM metadata. - -Author: Gabriel de Perthuis <g2p.code+augeas(a)gmail.com&gt; - -About: License - This file is licensed under the LGPL v2+. - -About: Configuration files - This lens applies to files in /etc/lvm/backup and /etc/lvm/archive. - -About: Examples - The <Test_LVM> file contains various examples and tests. -*) - -module Guestfs_LVM_conf = - autoload xfm - - (* See lvm2/libdm/libdm-config.c for tokenisation; - * libdm uses a blacklist but I prefer the safer whitelist approach. *) - (* View: identifier - * The left hand side of a definition *) - let identifier = /[a-zA-Z0-9_-]+/ - - (* strings can contain backslash-escaped dquotes, but I don't know - * how to get the message across to augeas *) - let str = [label "str".
