As far as I can tell, the problem ist related to faccessat2(), while in most cases there's a fallback to faccessat, this seems to fail, when it comes to sandbox: 157584 faccessat2(AT_FDCWD, "/var/tmp/portage/sys-apps/file-5.45-r1/temp/sandbox-misc.log", F_OK, AT_SYMLINK_NOFOLLOW|AT_EACCESS) = -1 ENOSYS (Function not implemented) 157584 lstat("/var/tmp/portage/sys-apps/file-5.45-r1/temp/sandbox-misc.log", 0x7ffd7c25b0c0) = -1 ENOENT (No such file or directory) 157584 access("/var/log/sandbox", W_OK) = 0 157584 getpid() = 157584 157584 faccessat2(AT_FDCWD, "/var/log/sandbox/sandbox-debug-157584.log", F_OK, AT_SYMLINK_NOFOLLOW|AT_EACCESS) = -1 ENOSYS (Function not implemented) 157584 lstat("/var/log/sandbox/sandbox-debug-157584.log", 0x7ffd7c25b0c0) = -1 ENOENT (No such file or directory) 157584 readlink("/proc", 0x7ffd7c25a1f0, 4088) = -1 EINVAL (Invalid argument) 157584 readlink("/proc/self", "157584", 4093) = 6 157584 readlink("/proc/157584", 0x7ffd7c25a1f0, 4093) = -1 EINVAL (Invalid argument) 157584 readlink("/proc/157584/fd", 0x7ffd7c25a1f0, 4096) = -1 EINVAL (Invalid argument) 157584 faccessat2(AT_FDCWD, "/usr/share/sandbox/sandbox.bashrc", F_OK, AT_SYMLINK_NOFOLLOW|AT_EACCESS) = -1 ENOSYS (Function not implemented) 157584 lstat("/usr/share/sandbox/sandbox.bashrc", {st_mode=S_IFREG|0644, st_size=3751, ...}) = 0

(In reply to Pavel from comment #6) That appears to be a different failure.
