Description Bruce Jerrick 2010-08-12 01:53:15 EDT
Description of problem: /sbin/mount.tmpfs will emit error messages at boot time, and fails to turn off restricted mode, if two conditions are met: 1. A tmpfs filesystem is used (listed in /etc/fstab). 2. /usr is a separate filesystem, mounted after a tmpfs filesystem. The problem is simply that /sbin/mount.tmpfs uses 'id', which is in /usr/bin/id, and hence not yet available. Version-Release number of selected component (if applicable): coreutils-8.4-8.fc13.i686 (The error message is emitted by /sbin/mount.tmpfs, but the easy fix is to coreutils; see "Additional info" below.) How reproducible: 100% Steps to Reproduce: Prerequisites: A tmpfs filesystem in /etc/fstab, e.g.: tmpfs /tmp tmpfs defaults 0 0 A separate /usr filesystem, listed after tmpfs in /etc/fstab . Then boot (single-user will do). Actual results: On the system console (also in /var/log/boot.log): Mounting local filesystems: /sbin/mount.tmpfs: line 22: id: command not found /sbin/mount.tmpfs: line 23: id: command not found /sbin/mount.tmpfs: line 25: [: -eq: unary operator expected Expected results: No error messages after "Mounting local filesystems". Additional info: Two possibilities to fix: 1. Change the location of 'id' from /usr/bin/id to /bin/id, in the coreutils package. 2. Make all the 'id' code in /sbin/mount.tmpfs be conditional on 'type -t id >/dev/null', and if that fails, assume it's boot time, and set restricted=0 . (No, I don't like it either.)
Comment 1 Bruce Jerrick 2010-08-12 01:56:46 EDT
It looks like the use of 'id' was introduced with rhbz 616393 .
Comment 2 Ondrej Vasik 2010-08-12 04:26:08 EDT
well... there are several binaries in coreutils which were moved from /usr/bin to /bin ... most recent one was readlink. Solution with keeping symlink in /usr/bin and moving binary into /bin is safe enough, however I don't want to polute /bin with more binaries. Anyway, id doesn't depend on anything from /usr/lib, so it is safe to move it. Karel, as you are the maintainer of /sbin/mount.tmpfs ... which possibility do you prefer?
Comment 3 Karel Zak 2010-08-12 09:11:46 EDT
oh... I don't need id(1) at all (see bug #620924). The bash provides all necessary information in $UID and $EUID. From my point of view you can close this issue.
