/boot too small

I've made a mistake when I decided on the partition sizes some years ago: The partition mounted on `/boot` is too small.  Occasionally, when updating (`pacman -Syu`), I get an error message that there is not enough disk sapace, and the entire update is cancelled.  Removing `/boot/initramfs-linux-fallback.img` before updating helps.

    $ df -h
    Filesystem        Size  Used Avail Use% Mounted on
    dev               488M     0  488M   0% /dev
    run               493M  660K  493M   1% /run
    /dev/mapper/root  233G   59G  174G  26% /
    tmpfs             493M   48K  493M   1% /dev/shm
    tmpfs             493M     0  493M   0% /sys/fs/cgroup
    tmpfs             493M  8.0K  493M   1% /tmp
    /dev/sda1          58M   42M   14M  76% /boot
    tmpfs              99M  4.0K   99M   1% /run/user/1000

    $ ls -l /boot
    total 40M
    -rw-r--r-- 1 root root  25M Aug 20 10:07 initramfs-linux-fallback.img
    -rw-r--r-- 1 root root 9.4M Aug 20 10:07 initramfs-linux.img
    drwx------ 2 root root  13k Jan  5  2016 lost+found
    drwxr-xr-x 2 root root 3.1k Mar  4 00:22 syslinux
    -rw-r--r-- 1 root root 5.5M Aug 18 16:09 vmlinuz-linux

What are my options, other than the obvious new installation from scratch?  I have an encrypted partition on `/` and AFAIK tools that change partition sizes cannot handle that.  Even if they did, I would not feel very comfortable doing that.

Thanks

Re: /boot too small

I had a similar issue with a / partition that was running low on space.
I used Gparted from a live CD to resize the partitions without needing to re-install.

As always when juggling partitions - backup first.

Mod note: not an installation issue, moving to NC.

Re: /boot too small

Just move the contents of /boot to a temp dir, then unmount /boot and finally move the temp dir to /boot on the mounted root filesystem.  Update your boot loader and problem solved.  There isn't a requirement for a separate /boot partition.

Also, I find no use for the fallback image so why generate it?  Edit /etc/mkinitcpio.conf and remove fallback.
