Maybe we can keep only bash-minimal? bash-static is used by glibc (for the 'system' function), it's not something that can simply be replaced with bash-minimal (due to the cycle bash-minimal -> glibc -> bash-minimal that would result). I do have a proposal eliminating the bash-static reference though: * replace the 'system' function from glibc by a variant that accepts the file name of the shell executable * Add a macro '#define system ...' that calls this variant and inserts __guix_bin_sh as the shell executable * In the build system, look for bin/sh in the inputs.  If it exists, add -D__guix_bin_sh=/gnu/store/.../bin/sh to CFLAGS or such.
