考虑以下 MWE （对于lualatex）：
\documentclass{article}
\usepackage{etoolbox}
\usepackage{fontspec}
\usepackage{biblatex}
\usepackage{bigfoot}
\begin{document}
Test
\end{document}
到目前为止，如果没有包和，TL15这将无法工作。现在不存在了，但不幸的是，这似乎会带来问题。我总是得到以下错误（实际上我得到了两次）：etex\reserveinsertsTL15 etexbigfoot
! No room for a new \count .
\ch@ck ...\else \errmessage {No room for a new #3}
\fi
l.621 \newinsert\FN@savebox
?
我猜问题在于bigfoot，但是由于\reserveinserts不再存在，我不知道如何解决这个问题。

如果您的内核版本过时，则可能会发生这种情况：虽然团队已努力使更改“透明”，但在某些情况下旧内核 ltluatex和第三方软件包之间的交互可能会出现问题。
使用最新的 TeX 系统，最新内核的源代码将可用。强制重建格式取决于您的 TeX 系统。对于 TeX Live（包括 MacTeX），最简单的方法是在终端上执行
sudo fmtutil-sys --refresh
对于 MiKTeX，从开始菜单上的 MiKTeX 维护条目中，选择设置，然后选择更新格式。
请注意，该etex包仍然可用，因此对于较旧的格式，方法
\RequirePackage{etex}
\reserveinserts{40}
...
将工作。
