In Linux distributions, the system are already divided into many small packages. On the other hand, BSD Unix variants are behind the curve on the base system packaging. To improve NetBSD base system granularity, we have developed a software “basepkg” by making the best use of pkgsrc framework. It is shorter than the existing base packaging framework syspkg, easy to understand and an almost POSIX compliant shell script for more sustainable maintenance. Also we operate an experimental base package distribution server to evaluate our software in realistic environment. It is shown that basepkg provides faster replacement of a few OS granular parts and extra useful functions. It must be beneficial for NetBSD users and customers.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告システムソフトウェアとオペレーティング・システム（OS）"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2018-02-20","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"6","bibliographicVolumeNumber":"2018-OS-142"}]},"relation_version_is_last":true,"weko_creator_id":"11"},"created":"2025-01-19T00:53:04.607967+00:00","id":186019,"links":{}}
