+### Please describe the problem.
+
+The install script [[install/Android/git-annex-install]] only adds an entry to `$PATH` which lasts for as long as the shell used for the install.  Subsequent launches of termux will not find `git-annex` on the `$PATH`.
+
+I'm puzzled why this hasn't been reported before.  Is everyone on Android manually running `./git-annex.linux/git-annex ...` each time, or have they manually set up `$PATH` in their Termux shell profile without reporting back to the community, or am I missing something else?
+
+### What steps will reproduce the problem?
+
+- Install `git-annex` on Android as per [[Android]]
+- Quit the shell used during install
+- Relaunch termux
+- Try to run `git-annex`
+
+### What version of git-annex are you using? On what operating system?
+
+6.20180927-gc5b6c55af on Android P
+
+I know this is probably old now but I can't see any evidence the installer fixed this issue since I last tried.  Happy to be told I'm wrong.
+
+### Please provide any additional information below.

+
+Yes, been using it for many years and couldn't live without it.

+### Please describe the problem.
+
+When following the instructions in [[tips/unlocked files]] on Mac, I am seeing an error message when smudge is run.
+
+This causes the file to end up in git's object database (`.git/objects`) instead of git annex's (`.git/annex/objects`).
+
+I tried the same steps on linux with the autobuilder version (7.20190508) and got no error and the data ended up in git annex correctly.

+YES! Git annex is an amazing tool and it's the backbone of my long term archiving workflow. I also use it for archive management at work and it's proven to be incredibly useful. Thank you for continuing to maintain and innovate with git annex!

+\"I don't see any way to do checksum verification on upload to a special remote, without it somehow having a way to verify an arbitrary checksum method of data stored in it, which nothing supports\" -- arbitrary checksum no, but some remotes do support verifying MD5 checksums specifically.  E.g. DNAnexus can tell you the MD5 of each uploaded part of a multi-part file; Google Cloud Storage can tell you the MD5 for a non-composite file, and CRC32 for composite files. Maybe, the [[external special remote protocol|design/external_special_remote_protocol]] could be extended with optional requests/replies to expose these capabilities?
