Public bug reported:
Binary package hint: console-setup
Ubuntu 8.10
console-setup, Version: 1.25ubuntu4
If you have multiple kernels installed, executing
dpkg-reconfigure console-setup
will update the /boot/initrd.img-* file that is linked to by
/initrd.img. That link normally points to the /boot/initrd.img-*
file used with the kernel which was most recently installed. So,
if you happen to be using another kernel, the wrong file is updated.
If that happens, the changes will be made to the console, as expected,
but the next time the user reboots with that kernel, the console will
revert to its previous state. Adding to the confusion is the fact that
executing "dpkg-reconfigure console-setup" again will provide default
answers matching those supplied before, and accepting those defaults
will again make changes to the console, as expected. But the console
will again revert to its previous state on the next reboot to that
kernel.
To reproduce:
1. If you have only one kernel installed, install another kernel
package (not just a different version of your current package).
2. Note that the soft link at /initrd.img points to the the
/boot/initrd.img-* file corresponding to the most recently
installed kernel.
3. If you are using the most recently installed kernel, reboot and
select another from the grub menu.
4. Run
sudo dpkg-reconfigure console-setup
and change the font and/or the font size.
5. Note that the font changes as expected.
6. Reboot and select the same kernel you just used.
Actual results: the font has reverted to its old state.
Expected results: the font is as configured in step 4.
The seems to be in /var/lib/dpkg/info/console-setup.postinst.
Near the bottom of that script is this line:
update-initramfs -u
When given the -u option, update-initramfs always prefers the file
linked to by /initrd.img, if it exists. Perhaps that one line could
be replaced by the following three lines (which were borrowed from
update-initramfs itself, and modified appropriately):
if [ -f /boot/initrd.img-`uname -r` ]; then
update-initramfs -u -k `uname -r`
fi
This works for me, although I've not done any extensive testing.
(This bug may be a duplicate of LP:345145 and/or LP:410335, but it is
not clear if those bugs have the same root cause as this one.)
