Red Hat Bugzilla – Bug 238437
Encrypted /tmp partition does not quite work
Last modified: 2014-03-16 23:06:27 EDT
(This is the latest devel as of April 29th.) Configuring /tmp using crypttab does not quite work. Here are the options I used: in /etc/crypttab: > crypt_tmp /dev/lucius_vg/ /dev/random tmp in /etc/fstab: > /dev/mapper/crypt_tmp /tmp defaults 0 0 The trouble is, init tries to mount the partitions *before* the "RNG" step of cryptsetup is run, which results in a failure to mount /tmp, since /dev/mapper/crypt_tmp is not there until RNG cryptsetup is run. This is possibly a chicken-and-egg problem, since mounting partitions may be required before /dev/random can be used, but the problem exists nonetheless.
Problem still exists as of Fedora 8 Test 3.
Based on the date this bug was created, it appears to have been reported against rawhide during the development of a Fedora release that is no longer maintained. In order to refocus our efforts as a project we are flagging all of the open bugs for releases which are no longer maintained. If this bug remains in NEEDINFO thirty (30) days from now, we will automatically close it. If you can reproduce this bug in a maintained Fedora version (7, 8, or rawhide), please change this bug to the respective version and change the status to ASSIGNED. (If you're unable to change the bug's version or status, add a comment to the bug and someone will change it for you.) Thanks for your help, and we apologize again that we haven't handled these issues to this point. The process we're following is outlined here: http://fedoraproject.org/wiki/BugZappers/F9CleanUp We will be following the process here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping to ensure this doesn't happen again.
This is not just limited to /tmp. Any Logical Volume will not yet have been activated at the time that sysinit attempts to set up encrypted volumes. LVM only activates volumes after crypttab is read and unencrypted. This is the desired behavior if you want to encrypt an entire partition but not the desired behavior if you want to encrypt an LVM volume. Methinks the only way to fix this is to attempt to unencrypt volumes twice, once before and once after LVM is set up. Also, the problem exists in RHEL 5.1 -alan

This message is a reminder that Fedora 8 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 8. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '8'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 8's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 8 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping

Fedora 12 changed to end-of-life (EOL) status on 2010-12-02. Fedora 12 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. Thank you for reporting this bug and we are sorry it could not be fixed.
