Subject: [bug#57050] [PATCH 2/6] gnu: stex: Fix read-only gifs and math directories.
Date: Mon,  8 Aug 2022 02:10:03 -0400

Excplicitly set the user write bit when initializing the gifs or math
directories from the skeletons installed in the store. See also upstream
discussion at <https://github.com/dybvig/stex/pull/6>. This problem
would be exposed by the upcoming changes to Racket's build system.

* gnu/packages/patches/stex-copy-from-immutable-store.patch: New patch.
* gnu/local.mk (dist_patch_DATA): Add it.
* gnu/packages/chez.scm (stex-bootstrap)[patches]: Use it.
[version]: Increment revision to 1.2.2-3.afa6075.

+Subject: [PATCH] fix read-only gifs and math directories
+
+An installed copy of stex might have all write permission bits removed,
+even for the owner of the installed files: this is the case with Guix
+package of stex, for example. If such an installation is used to
+initialize the gifs or math directories (e.g. for an out-of-source
+build), tar likewise creates them without write permissions, preventing
+subdirectories from being created later. Set the user write bit
+explicitly to avoid this problem.
