Bug#774227: busybox-static: execs applets when chrooting
Package: busybox-static
Version: 1:1.22.0-14
Severity: important
Tags: patch
#599101 is back, at least in busybox-static (I have not not tested the other one):
Things like chroot /target dpkg ... do not call dpkg but instead call
busybox's internal command (which leads to quite hard to debug error
messages trying to run debootstrap).
To fix it the same patch as before is needed, which is also the
end of debian/patches/applets-fallback.patch.sav:

+ execvp(argv[0], argv);
+ xfunc_error_retval = (errno == ENOENT) ? 127 : 126;
+ bb_perror_msg_and_die("can't execute '%s'", argv[0]);
}
