我在我的 manjaro 机器上安装了 texlive 2023。当我使用 luathex 编译我的 tex 文件时，我可以在输出日志中看到以下几行：
luaotfload | db : Font names database not found, generating new one.
luaotfload | db : This can take several minutes; please be patient.

当我跑步时kpsewhich -var-value=TEXMFCACHE
我得到/home/hafid/texlive/2023/texmf-var:/home/hafid/.texlive2023/texmf-var
当我跑步时luaotfload-tool -u
我得到

问题：/home/hafid/texlive/2023/texmf-var/luatex-cache/generic/names
在 texlive 安装期间没有创建目录：这很正常吗？
