+++ This bug was initially created as a clone of Bug #808907 +++
Description of problem:
/var/lib/random-seed file is not functional under readonly root enabled. This file cannot be removed due to "Read-only file system" error and the system will show the error message when booting: "systemd-random-seed[517]: Failed to write new random seed file: Bad file descriptor".
Version-Release number of selected component (if applicable):
initscripts-9.34.2-1.fc16.x86_64
How reproducible:
100%
Steps to Reproduce:
1. Just install base and core groups
2. Enable readonly root function in /etc/sysconfig/readonly-root file, set READONLY=yes and TEMPORARY_STATE=yes.
3. Add mount option ro in /etc/fstab for / directory.
4. Reboot
Actual results:
"systemd-random-seed[517]: Failed to write new random seed file: Bad file descriptor" and the file cannot be removed/modified.
Expected results:
No error for /var/lib/random-seed.
Seeing the same error in Fedora 18 alpha still.
Hi, this is not bug in readonly-root, but in systemd-random-seed.service. Adding fedora-readonly.service to systemd-randomd-seed's After solves this issue - /var/lib/random-seed is bind mounted as rw before it is used.
-After=systemd-readahead-collect.service systemd-readahead-replay.service systemd-remount-fs.service
+After=systemd-readahead-collect.service systemd-readahead-replay.service systemd-remount-fs.service fedora-readonly.service
There is another issue with selinux involved bz #921456.
