Depends on the POV, I guess: Seen from Samba, the long hostname is an issue. Seen from Jenkins, Samba should do better. In the comparable samba/debci case, debci has a pending fix (netbios compliant hostname).

Might be better, yes. Maybe the Samba maintainers would accept something like this: --- a/samba-common-bin.postinst 2018-06-06 14:13:40.612764675 +0200 +++ b/samba-common-bin.postinst 2018-06-06 14:28:30.645949184 +0200 @@ -3,7 +3,14 @@ set -e echo "Checking smb.conf" -samba-tool testparm -d1 --suppress-prompt > /dev/null +if [ $(hostname|wc -m) -le 15 ] ; then + samba-tool testparm -d1 --suppress-prompt > /dev/null +else + echo "WARNING: The hostname is too long to serve as netbios name." + echo "Please set a valid netbios name, see man (5) smb.conf for details." + testparm -d1 -s --option='netbios name = test' > /dev/null +fi echo "Done" +#DEBHELPER# -------------------------------------------------------------- It would only warn instead of erroring out in case of too long hostnames.
