1. Run composer create-project acquia/blt-project --no-interaction
2. Run blt recipes:acsf:init:all

Expected behavior
factory-hooks/post-site-install/post-site-install.sh should have the same permissions as factory-hooks/db-update/db-update.sh

Looks like a regression introduced when that script was renamed: #4061

Fixed in 11.x and 12.x:

• Fix #4257: ACSF post-site-install.sh not executable #4264
• acquia/blt-acsf@1b75a5a
