Running make with `-j4` sometimes causes errors

[GamePlayer-8]

Hello,

Whenever I am building the s6-overlay with make -j4 ARCH="x86_64-linux-musl" VERSION="v3.2.2.0", from time to time I'm getting an error related to the missing execline:

The error is totally gone whenever using -j1 or by removing the argument, in an exchange of reducing the build speed.

Thanks for the report! Indeed, the make install parts need to be serialized, but the rest of the builds can run in parallel. I need to find the right invocation for this.

Edit: I just added -j1 to the make install invocation. If you can build s6-overlay from the git repository, can you please test whether it fixes the issue?

From my tests it builds correctly as of now.

(temporary the bearssl git host is down, so wasn't been able to run enough build cycles to determine)

Thanks. Not sure when I'll be able to cut a new release; some time this year.

The bearssl git host is up, just extremely slow to respond. I suspect it's under attack by LLM crawlers, as are most sites nowadays 😦

I've contacted the sysadmin behind bearssl host before and afaik is DDoS / aggressive LLM crawling
