Title:
Busybox mount fails to mount Snaps
Status in busybox package in Ubuntu:
Expired
Bug description:
Snapd tries to mount squashfs Snaps with non-standard mount flags like
"x-gdu.hide" and "x-gvfs-hide", both of which are used to indicate to
userspace programs that a given mount should not be shown in a list of
mounted partitions/filesystems. Busybox does not support these flags,
and so fails with "Invalid argument".
$ sudo busybox mount -t tmpfs -o x-gdu-hide test /tmp/test
mount: mounting test on /tmp/test failed: Invalid argument
These flags can likely be be safely ignored, as they don't actually
affect the functionality of the mount. This goes for all mount options
starting with "x-", as these generally denote non-standard mount
option "extensions".
I've created a patch against Busybox which adds an optional
configuration item to ignore all mount options beginning with "x-". An
additional verbose option has also been added to enable the ability to
report that the mount flags have been ignored, rather than silently
ignoring them.
This is a requirement for a customer project, where we are limited to
using Busybox (due to coreutils' GPL-3.0 licence) but would also
require using Snaps like checkbox for testing and verification. This
was posted on the Busybox mailing list a few months ago
(http://lists.busybox.net/pipermail/busybox/2023-March/090202.html)
but patch acceptance there seems to take quite a long time, and we
need this for the customer.
A PPA containing the patched Busybox version is available on the
