Comment 5 for bug 2058409

The postinstall runs fails because luatex now has the 'socket' functionality disabled by default. [CVE-2023-32668]

The upstream source for mtxrun has --socket added to the luatex command line to reenable the functionality while running 'mtxrun --make'. See lines having '--socket' in https://source.contextgarden.net/mtxrun.lua

I think that there are two bugs here:
1) The mismatch between luatex and context regarding --socket, and
2) The post-install hangs indefinitely rather than returning an error.
