No support for locale: en_US.utf8
by dervish on Jun.18, 2012, under Linux, Ubuntu
Error:
update-initramfs: Generating /boot/initrd.img-3.0.0-12-generic
Warning: No support for locale: en_US.utf8
Issue:
The problem is that /usr/share/initramfs-tools/hooks/root_locale is expecting to see individual locale directories in /usr/lib/locale, but locale-gen is configured to generate an archive file by default.
Fix:
# locale-gen --purge --no-archive

Dist Switch
by dervish on Jul.26, 2011, under CentOS, Linux
Switched to CentOS 6 as my primary Linux OS. Fedora is getting the boot after many, many, years of use. Fedora 15 just has too many things that are wrong with it. In all fairness, some of the issues are with the path Gnome and Linux has taken in general. It was a good run.
