I've also not run out of inodes on my ext4 system that was set up with
Debian's defaults.
Also, it may be better to recommend creating the filesystem with more
inodes than usual, rather than reducing the size of the inodes. From the
man page mkfs.ext4(8):
-N number-of-inodes
Overrides the default calculation of the number of inodes that
should be reserved for the filesystem (which is based on the
number of blocks and the bytes-per-inode ratio). This allows the
user to specify the number of desired inodes directly.
But then you are really asking for too much expertise when installing
Guix, in my opinion.
