Hi,
when comparing 12.0.0 with 11.5.0 i see three file trees which have grown
substantially:
du of mounted debian-11.5.0-amd64-netinst.iso :
5 /firmware
126611 /install.amd
308479 /pool
du of mounted debian-12.0.0-amd64-netinst.iso :
221108 /firmware
156509 /install.amd
589416 /pool
In pool of 12.0.0 i see another firmware tree
220570 /pool/non-free-firmware
but this does not cost much media capacity, because the file content is
shared with the files in the /firmware tree:
$ xorriso -indev debian-12.0.0-amd64-netinst.iso \
-find / -sort_lba -exec report_lba --
...
Report layout: xt , Startlba , Blocks , Filesize , ISO image path
...
File data lba: 0 , 18420 , 8217 , 16827872 ,
'/firmware/firmware-atheros_20230210-5_all.deb'
File data lba: 0 , 18420 , 8217 , 16827872 ,
'/pool/non-free-firmware/f/firmware-nonfree/firmware-atheros_20230210-5_all.deb'
...
Such deduplication of hard links also happens with initrd.gz and vmlinuz
files in /install.amd. The real storage sizes as measured in above -find
output are:
11.5.0 12.0.0 Growth
/firmware 0 MiB 216 MiB 216 MiB
/install.amd 67 MiB 138 MiB 71 MiB
/pool 301 MiB 360 MiB 59 MiB
To fit on a regular "700 MB" (~ 702 MiB) CD-R/CD-RW these would have to
shrink by at least 36 MiB.
Have a nice day :)
