In Samsung N910U (Android 6.0.1) , The Internal SD Path shoud be /storage/emulated/0
When I use fmount -b "WhatsApp" ".foldermount/WhatsApp"
WhatsApp still write into Internal SD (/storage/emulated/0 )
".foldermount/WhatsApp" not mount in "/storage/emulated/0/WhatsApp"

The regex validating the Sd card doesn't work on my phone running RR (based on lineage for athene), as the uuid uses lower case letters.

Changing '[0-9AF]{4}-[0-9A-F]{4}' to '[0-9a-fA-F]{4}-[0-9a-fA-F]{4}' worked for me.

Ok folks, some people still reported issues with not properly mounted folders and I asked them to send me a screenshot with the output of mount.

So the reason why it's not working is because their SD cards are formatted using Windows proprietary exFAT, which is known for causing problems on Linux kernel based systems like Android does. In that case I would suggest you to reformat the SD card using FAT32 (vfat) on a PC and then it should work.

TL;DR: SD cards formatted using exFAT aren't compatible and therefore not supported by me.

Hi!

First of all, thanks for all of your work!

I am just wondering what is the licence for this code? I made some changes, including implementing some basic form of listFunc and rebindFunc. Just wondering about the licence before I push the changes to my fork :)

Thanks!

What is the goal?

This module aims to be a alternative solution to FolderMount, a app created by madmack, but unfortunately his app does not work with MagiskSU anymore.

Milestones

v0.8.5

• Find alternative way to mount folders on boot (done, see commit 7edb864)
  The current method doesn't work when fmount is executed in post-fs-data on boot

v0.8.9

• Revert new method and find out what's the cause folders won't mount (done, see 61b2a9f)
  New method does not have fixed this issue with v0.8.5, so we need to investigate more into that
• Better command line output
  Currently the error messages and help output are not very helpful, these need to be reworked

v0.9

• Ability to save mounted folders to a list and mount them after a reboot
  This could be done by writing a script which will be executed at post-fs-data
• listFunc()
  This function should list all folders and check whether these are mounted or not and print them out
• rebindFunc()
  This function should remount all folders which are in $BINDLIST (some sort of list parsing needed)

v1.0

• Possibility to unmount a folder without removing it from the list
  Like in the original FolderMount, there should be a possibility to temporarily unmount a folder
• Option to skip moving files from/to destination folder before mounting/unmounting
  To make integration into custom scripts or future apps easier, this should be done from the script
