Hi, debian-9.3.0-amd64-netinst.iso was made with xorrisofs option -joliet-long, which enable Joliet names longer than 64 characters. But production of debian-9.3.0-amd64-DVD-2.iso did not use it.
Whatever setting is finally desirable, it should be the same with all Debian ISOs which get a Joliet filesystem tree by option -J. I stumbled over this by https://lists.debian.org/debian-user/2018/02/msg00388.html: > From: Serge LAOT <serge.l...@wanadoo.fr> > Date: Fri, 9 Feb 2018 18:22:56 +0100 > [...] > I have found some discrepencies between filenames in './pool/main/' and > the filenames in 'md5sum.txt'. > [...] > ./pool/main/m/mono/libmono-compilerservices-symbolwriter4.0-cil_4.6.2.7+dfsg-1_all.deb > ./pool/main/m/mono/libmono-compilerservices-symbolwriter4.0-cil_4.6.2.7+dfsg-1_a.deb ------------------------------------------------------------------ Details: If i download https://cdimage.debian.org/debian-cd/current/amd64/iso-dvd/debian-9.3.0-amd64-DVD-2.iso and mount it without disabling Rock Ridge, i see the longer name /mnt/iso/pool/main/m/mono/libmono-compilerservices-symbolwriter4.0-cil_4.6.2.7+dfsg-1_all.deb If i mount the Joliet tree by "-o norock", i see the truncated name /mnt/iso/pool/main/m/mono/libmono-compilerservices-symbolwriter4.0-cil_4.6.2.7+dfsg-1_a.deb This truncation is caused by xorrisofs option -J without a specs relaxation option like -joliet-long. The truncated length of 65 is correct, because Joliet prescribes 128 bytes which suffices for 64 UTF-16 characters. The dot in the name does not count for that limit. Looking at the files .disk/mkisofs of debian-9.3.0-amd64-DVD-2.iso and debian-9.3.0-amd64-netinst.iso reveils that netinst had -joliet-long whereas DVD-2 had not. Have a nice day :) Thomas
