we deployed “mousepad” for users who want’s to create some offline notes.
Which path can they used for saving their notes on the IGEL OS? If they save them somewhere below /userhome it will be lost after rebooting.
Hi Eric, the best way would be to create a custom Partition with 50Mb and save it there. This one will stay persistent and don‘t represent a security issue.
So either, as @member said for a CP called something like /custom/Documents, or if the notes files are small (say 5 MB or so) then:
ln -s /wfs/user/Documents /userhome/Documents
Thanks, I like Ron’s solution a little bit more.
What’s the best section to insert these commands? I also noticed that I have to change the permission of the folder with “chmod” to avoid access denied message.
@member just a note on storing stuff in /wfs: please never get out of sight that a filled up wfs mount point can result in undefined failures of IGEL OS.
Just keep in mind to check that in first place if something weird like restarting devices or if no profiles can be applied anymore. it has to stay on the level Ron described, <5mb
Maybe something like this…
It sounds like if the WFS partition is filled up with data, the IGEL may experience some seemingly “random issues”. Is there anyway to limit the user or set a disk quota for this purpose?
Well, there isn‘t even if it could be integrated. In the past wfs wasn‘t accessible from User because of Security issues, I‘m still thinking /wfs should be kept free of User interactions ☺️
I can see that the wfs partition is 512MB. At the moment there is only 2MB/512MB in used.
So alot of empty space. But again for these notes it should never neeed more then 5MB. Can you maybe give me a hint, how a user can simply delete a file in this folder?
Well, /wfs may look like 512MB… I think 25MB is real size… /wfs/ is not a “normal” filesystem, it has it’s own wfsd daemon. And mechanisms like file locks, .. doesn’t work as expected.
I was giving some thoughts how to implement a user quota within IGEL. One method could be to create a loopback file containing a filesystem (ie. fixed size of 2MB), and mounting this in the userhome space. It’s a bit more work to setup, but it will limit the user from being able to write more than the 2MB to this mount/directory. Something like Mousepad will show a “No space left on device” prompt when attempting to save when no space remains.
Negatives: more setup, it will occupy the full size (2MB) from the start, and it will be more steps to troubleshoot.
(This could also be used in the /custom partition to setup a “user quota”)
There are lots of comments/journal logging here, so it’s a little long.
# create loopback file and filesystem, if it doesn’t exist.
