Bug#844150: jessie-pu: package lxc/1:1.0.6-6+deb8u4
Package: release.debian.org
Severity: normal
Tags: jessie
User: release.debian.org@packages.debian.org
Usertags: pu
Ohai,
we would like to fix two bugs in LXC in stable:
#838517 lxc-alpine template broken
simple one-line patch to tell OpenSSL which hashing algo to use
#838957 read-only bind mounts are in fact read/write
another quite short patch to trigger remounting bind mounts as RO
Full debdiff attached.
Thanks in advance
Evgeni

+Subject: [PATCH] Remounts bind mounts if read-only flag is provided
+
+Bind mounts do not honor filesystem mount options. This change will
+remount filesystems that are bind mounted if there are changes to
+filesystem mount options, specifically if the mount is readonly.
