Hi,

On 19.07.3, the listed lineup of packages has 5.54M and it fits:

Exportable Squashfs 4.0 filesystem, xz compressed, data block size 262144
	compressed data, compressed metadata, compressed fragments,
	no xattrs, compressed ids
	duplicates are removed
Filesystem size 5674.78 Kbytes (5.54 Mbytes)
	35.35% of uncompressed filesystem size (16051.56 Kbytes)
Inode table size 13736 bytes (13.41 Kbytes)
	22.46% of uncompressed inode table size (61170 bytes)
Directory table size 17662 bytes (17.25 Kbytes)
	44.53% of uncompressed directory table size (39661 bytes)

Yes, but I was wondering why the image gets 300Kb bigger on 20.xx.
