Bug#833231: initramfs-tools: during initramfs: "/init: line 1: logsave: not found" when e2fsprogs is not installed

[Daniel Kahn Gillmor <dkg@fifthhorseman.net>]

Source: initramfs-tools
Version: 0.125
Severity: normal
Control: affects -1 e2fsprogs

I have a minimal system with only btrfs filesystems, and e2fsprogs is
not needed on it.  It would be nice to be able to uninstall it.

however, when i uninstall e2fsprogs and reboot into an initramfs built
by initramfs-tools, i see the following error and then i get dropped
back into the initramfs shell:

(initramfs) exit
/init: line 1: logsave: not found
The root filesystem on /dev/vda1 requires a manual fsck


BusyBox v1.22.1 (Debian 1:1.22.0-19) built-in shell (ash)
Enter 'help' for a list of built-in commands.

(initramfs) 


even if i remove the logsave and "requires a manual fsck" lines from
/scripts/functions in the initramfs, these errors repeat themselves
and i can't get the system booted again.

It would be nice to remove the need for e2fsprogs for systems that
aren't using the extX family of filesystems.
