[SOLVED]Little space remained in /boot

After the latest firmware update (more than a month ago) at the boot, I am a message that in the partition /boot only 26 MB of space remained.
It had already happened to me a few years ago and I had solved by setting the compression of the images before and I had never had problems.

At the moment I avoid updating the system because I have important works on the PC to finish and I cannot risk.

A possible solution could be that of bump up the image compression level but i think have yet maximum level.
At the moment I have XZ (-9e) and this is the maximum value permitted.
How could I minimize the space without risk?

mkinitcpio.conf

#COMPRESSION="zstd"
#COMPRESSION="gzip"
#COMPRESSION="bzip2"
#COMPRESSION="lzma"
COMPRESSION="xz"
#COMPRESSION="lzop"
#COMPRESSION="lz4"

# COMPRESSION_OPTIONS
# Additional options for the compressor
COMPRESSION_OPTIONS=(-9e)

Re: [SOLVED]Little space remained in /boot

lsinitcpio /boot/initramfs-linux.img # likely bloated by nvidia firmware?

and if you've usb key with grml or the arch install iso, you don't really *need* the fallback image, see /etc/mkinitcpio.d/linux.preset

Re: [SOLVED]Little space remained in /boot

I "fixed" adding kms.

fallback_options="-S autodetect,kms"

I think I understood that I would no longer have the backup of Nvidia but I think in this case I could manually remedy somehow.

Now my fallback is about 200Mb instead of 500Mb.

You can also enable the MODULES_DECOMPRESS, it made a big difference for me.
