A very similar "ENOTSUP" problem is being reported with coreutils-8.32 with `mknod -m 666 /dev/random c 1 8` when trying to build Fedora rawhide in a chroot. https://bugzilla.redhat.com/1811038 BTW I see a possible small issue in lchmod.c in this code: + if (chmod_errno != ENOENT) + { + errno = chmod_errno; + return chmod_result; + } Shouldn't that also check for other lookup errors like ENOTDIR and ELOOP ? Also mknod() in coreutils is calling lchmod(). Shouldn't it be just calling chmod() as if mknod() was passed a symlink, then it would have already failed with EEXIST? cheers, Pádraig
