External storage devices are successfully mounted to /run/media/myuser/ via udisks2 (udisksd service). I can read data from devices. However I can NOT write to them. I'm trying to edit directory ACLs in order to get write permissions for regularmyuser` I'm logged in with (not root)
Default permissions are as follows:
getfacl /run/media
getfacl: Removing leading '/' from absolute path names
# file: run/media
# owner: root
# group: root
user::rwx
group::r-x
mask::r-x
other::r-x
getfacl /run/media/myuser
getfacl: Removing leading '/' from absolute path names # file: run/media/myuser
# owner: root
# group: root
user::rwx
group::---
mask::---
other::---
getfacl /run/media/myuser/mydisk
getfacl: Removing leading '/' from absolute path names
# file: run/media/myuser/mydisk
# owner: myuser
# group: myuser
user::rwx
group::---
other::---
The above default setup prevents me from writing data to mounted device /run/media/mydisk. I tried to add write acl permission to myuser for /run/media/myuser dirrectory.
getfacl /run/media/myuser
getfacl: Removing leading '/' from absolute path names
# file: run/media/myuser
# owner: root
# group: root
user::rwx
user:myuser:rwx
group::---
mask::rwx
other::---
However that did not change anything.
Please note that I'm not able to write any data to the mounted device even with sudo elevated myuser.
Please, how can I solve the issue so I can write data to the mounted devices?
