I suspect ZFS-on-Linux (right?) is doing something unusual here:
mount(2) specifies the following reasons for EACCESS, and I don’t see
anything that would apply:
--8<---------------cut here---------------start------------->8---
EACCES A component of a path was not searchable. (See also path_resolution(7).)
EACCES Mounting a read-only filesystem was attempted without giving the
MS_RDONLY flag.
The file system may be read-only for various reasons, including:
it resides on a read-only optical disk; it is resides on a device
with a physical switch that has been set to mark the device read-
only; the filesystem implementation was compiled with read-only
support; or errors were detected when initially mounting the
filesystem, so that it was marked read-only and can't be
remounted as read-write (until the errors are fixed).
Some filesystems instead return the error EROFS on an attempt to
mount a read-only filesystem.
EACCES The block device source is located on a filesystem mounted with
the MS_NODEV option.
--8<---------------cut here---------------end--------------->8---
What do the following commands do on this system?
--8<---------------cut here---------------start------------->8---
$ mkdir -p /tmp/test/lib
$ unshare -mrf mount /lib /tmp/test/lib -o bind,readonly
--8<---------------cut here---------------end--------------->8---
Thanks,
Ludo’.
