RHBA-2005:223 - Bug Fix Advisory
Synopsis
am-utils bug fix update
Type/Severity
Bug Fix Advisory
Topic
Updated am-utils packages that remove possible mtab corruption are now
available.
Description
The am-utils packages include Amd, the popular BSD automounter, as well as
support tools.
Previous versions of am-utils used a different method for locking
/etc/mtab. In the presence of another automounter (AutoFS4) these earlier
versions could cause inadvertent mtab corruption under certain conditions
(where parallel mounts via both of the automounters were triggered in a
non-trivial count). A potential problem with am-utils and hand-mounting
also exists, but is much less immediate.
This release should fix most problems where only a few competing mounts are
run at once. However, if your automounters carry out several tens or
hundreds of mounts, the problem may persist, requiring an update of the
util-linux package (which includes the /bin/mount program) to remedy it.
Users should upgrade to these updated packages, which resolve these
issues.
Solution
