Re: Why doesn't Guix build static libraries?

I'll speak for myself: I remove static .a libraries whenever 
they're not obviously required by other software in Guix.  If 
another package were to require them, I'd first try to fix it to 
link dynamically.

Static linking provides no serious advantages and at least one 
serious disadvantage: it's invisible to grafting.  If A statically 
links to B, grafting B will leave A untouched and vulnerable.

My worry is that leaving .a files around will cause some build 
systems to silently prefer them to the .so and link statically.  I 
can't remember the name of the packages, but this does happen.

Static linking is useful in tightly-controlled environments where 
space is at a premium, i.e., the Guix System initrd.  That's why 
Guix has packages like bcachefs-tools-static.  It's just made very 
explicit.

Kind regards,
