Package: mount
Version: 2.25.1-3
Severity: normal
Since I upgraded mount from 2.20.1-5.11 to 2.25.1-3,
"mount --bind -o remount" doesn't preserve flags anymore.
# mount -V
mount from util-linux 2.20.1 (with libblkid and selinux support)
# grep /tmp /proc/self/mountinfo
24 15 0:22 / /tmp rw,nosuid,nodev,relatime - tmpfs /tmp rw
# strace -e trace=mount mount --bind -o remount,noexec /tmp
mount("tmp", "/tmp", 0x4104a4,
MS_MGC_VAL|MS_NOSUID|MS_NODEV|MS_NOEXEC|MS_REMOUNT|MS_BIND, NULL) = 0
+++ exited with 0 +++
